Replacement verdict
Compatible functional replacement candidate
The ADS5463IPFP and ADS5423IPGPR are both 14-bit high-speed analog-to-digital converters offering strong functional overlap, but they differ in sample rate, package footprint, and power consumption. The ADS5463IPFP is a viable functional substitute for the ADS5423IPGPR in many designs, provided the higher sampling rate and different package are validated against the target application's timing, thermal, and board-layout requirements.

Key electrical and mechanical differences between the two devices
| Parameter | ADS5463IPFP | ADS5423IPGPR | Why it matters |
|---|---|---|---|
| Resolution | 12 bit | 14 bit | Bit depth determines the quantization granularity and achievable SNR; a 14-bit ADC provides finer resolution than a 12-bit device, so they are not drop-in substitutes where accuracy is critical. |
| Sampling Rate | 500 MSPS | 80 MSPS | Maximum sample rate defines the input bandwidth the converter can support; the much higher rate of the ADS5463 suits wideband/high-frequency capture, while the ADS5423 targets lower-speed applications. |
| Input Type | Differential | Differential | Both use differential inputs, which improve common-mode noise rejection and dynamic performance; matching input topology simplifies analog front-end reuse. |
| Output Interface | Parallel LVDS | Parallel CMOS | The digital output format must match the receiving FPGA/ASIC interface; LVDS versus CMOS signaling affects board routing, pin count, and EMI, so the interface is a key substitutability constraint. |
| Supply Voltage | 3.3 V analog / 3.3 V digital | 5 V analog / 3.3 V digital | Supply rails must be compatible with the existing power design; differing analog supply voltages require different regulation and decoupling, affecting direct replacement. |
| Power Consumption | Approximately 2.2 W | Approximately 1.4 W | Power dissipation drives thermal design and supply sizing; a higher-power device may require additional cooling or current headroom in the target system. |
| Package | 80-pin HTQFP (PFP) | 52-pin HTQFP (PGP) | Package footprint and pin count must match the PCB land pattern; different packages mean the parts are not physically interchangeable without a board redesign. |
| Operating Temperature Range | -40°C to +85°C | -40°C to +85°C | The industrial temperature range confirms both parts suit the same environmental conditions, so thermal environment is not a differentiator between them. |

Frequently asked questions
What are the key differences between the ADS5463IPFP and ADS5423IPGPR?
The ADS5463IPFP is a 12-bit, 500-MSPS analog-to-digital converter, while the ADS5423IPGPR is a 14-bit, 80-MSPS ADC. The ADS5463IPFP offers higher sampling speed with lower resolution, whereas the ADS5423IPGPR provides higher resolution at a lower sampling rate. Both are manufactured by Texas Instruments.
Are the ADS5463IPFP and ADS5423IPGPR pin-compatible?
No. The ADS5463IPFP is supplied in a 52-pin HTQFP (PFP) package, while the ADS5423IPGPR is supplied in a 52-pin HTQFP (PHP) package. Although both use 52-pin HTQFP packages, the pinouts and thermal pad configurations differ between the two devices, so they are not directly pin-compatible and require separate PCB layouts.
What are the input signal specifications for the ADS5463IPFP?
The ADS5463IPFP is a 12-bit ADC with a maximum sampling rate of 500 MSPS. It features a differential input with a 2-Vpp full-scale range and an analog input bandwidth of approximately 1.5 GHz, making it suitable for high-speed signal acquisition applications such as test and measurement and communications.
What are the input signal specifications for the ADS5423IPGPR?
The ADS5423IPGPR is a 14-bit ADC with a maximum sampling rate of 80 MSPS. It offers a differential input with a 2-Vpp full-scale range and is designed for high-resolution applications such as medical imaging, instrumentation, and baseband signal processing where dynamic range is critical.
What are the power supply requirements for these two ADCs?
Both the ADS5463IPFP and ADS5423IPGPR operate from a single 5-V analog supply and a 3.3-V digital supply. The ADS5463IPFP typically consumes about 2.2 W at 500 MSPS, while the ADS5423IPGPR consumes approximately 1.1 W at 80 MSPS. Designers should verify exact supply and power figures against the respective TI datasheets.
Can the ADS5463IPFP and ADS5423IPGPR be used interchangeably in an existing design?
No. Because the two devices differ in resolution (12-bit vs 14-bit), maximum sampling rate (500 MSPS vs 80 MSPS), package pinout, and power consumption, they cannot be used interchangeably without redesigning the PCB, clocking, and digital interface. A direct drop-in substitution is not supported.
What digital output interface do these ADCs provide?
Both the ADS5463IPFP and ADS5423IPGPR provide parallel CMOS-compatible digital output buses. The ADS5463IPFP outputs 12-bit data, while the ADS5423IPGPR outputs 14-bit data. The output timing and data valid signals should be reviewed in the respective TI datasheets to ensure proper FPGA or ASIC interfacing.
Which applications are best suited for each device?
The ADS5463IPFP, with its 500-MSPS sampling rate, is suited for high-speed applications such as digital oscilloscopes, radar, and wideband communications receivers. The ADS5423IPGPR, with its 14-bit resolution at 80 MSPS, is better suited for high-dynamic-range applications such as medical imaging, spectrum analyzers, and precision instrumentation.
