Replacement verdict
Not a drop-in replacement
The ADS5474IPFP and ADS5411IPGP are both 14-bit analog-to-digital converters, but they differ fundamentally in sampling rate, analog input bandwidth, package footprint, and power consumption. The ADS5474IPFP offers a significantly higher sampling rate and wider input bandwidth, while the ADS5411IPGP operates at a lower sample rate with a different package and power profile. These differences in speed, signal chain requirements, and board layout mean the two devices are not functionally interchangeable without redesign.

Key electrical and mechanical differences between the two devices
| Parameter | ADS5474IPFP | ADS5411IPGP | Why it matters |
|---|---|---|---|
| Resolution | 14 bit | 11 bit | Higher resolution provides finer quantization and better dynamic range, directly affecting measurement accuracy and SNR. |
| Sampling Rate | 400 MSPS | 105 MSPS | Maximum sample rate determines the input bandwidth the ADC can digitize, which is critical for high-frequency signal capture. |
| Input Type | Differential | Differential | Differential inputs improve common-mode noise rejection and even-order harmonic performance. |
| Supply Voltage | 3.3 V analog / 3.3 V digital | 3.3 V analog / 3.3 V digital | Supply voltage compatibility ensures the part can drop into an existing power rail design without level shifting. |
| Output Interface | Parallel LVDS | Parallel CMOS | The output interface must match the downstream FPGA/ASIC receiver; LVDS vs CMOS affects board routing, EMI, and pin compatibility. |
| Package | 80-pin HTQFP (PFP) | 52-pin HTQFP (PGP) | Package footprint and pin count determine PCB layout compatibility and whether a direct board swap is possible. |
| Analog Input Bandwidth | 1.4 GHz | 500 MHz | Input bandwidth limits the highest frequency signal that can be accurately sampled, affecting IF sampling capability. |
| SNR | 69.6 dBFS | 61.5 dBFS | Signal-to-noise ratio defines the achievable dynamic range and directly impacts bit-error performance in receiver chains. |
| Power Consumption | 2.2 W | 1.1 W | Power dissipation affects thermal design, supply sizing, and suitability for power-constrained systems. |

Frequently asked questions
What are the key differences between the ADS5474IPFP and ADS5411IPGP?
The ADS5474IPFP is a 14-bit, 400-MSPS analog-to-digital converter in a 100-pin HTQFP package, while the ADS5411IPGP is an 11-bit, 105-MSPS ADC in a 100-pin HTQFP package. The ADS5474IPFP offers higher resolution and a significantly faster sampling rate, whereas the ADS5411IPGP targets lower-speed, lower-resolution applications.
Are the ADS5474IPFP and ADS5411IPGP pin-compatible?
No. Although both devices are housed in a 100-pin HTQFP (PFP/PGP) package, they are different converter families with different pin functions and supply configurations. A direct drop-in replacement is not supported; the PCB layout and pin assignments must be verified against each respective datasheet.
What are the resolution and sampling rate specifications of each device?
The ADS5474IPFP provides 14-bit resolution with a maximum sampling rate of 400 MSPS. The ADS5411IPGP provides 11-bit resolution with a maximum sampling rate of 105 MSPS. These differences directly affect achievable SNR, ENOB, and signal bandwidth in the target system.
Do both converters use the same output interface?
No. The ADS5474IPFP provides parallel LVDS-compatible output data, while the ADS5411IPGP provides parallel CMOS-compatible output data. The receiving FPGA or DSP interface must be configured accordingly, and level translation may be required when migrating between the two devices.
What are the typical power supply requirements for each part?
The ADS5474IPFP operates from a 5 V analog supply and a 3.3 V digital supply. The ADS5411IPGP operates from a 3.3 V analog supply and a 3.3 V digital supply. Power supply design and decoupling networks must be reviewed when considering a change between these devices.
Can the ADS5411IPGP be used as a lower-cost substitute for the ADS5474IPFP?
Only if the system can tolerate reduced resolution (11-bit vs 14-bit) and a lower maximum sampling rate (105 MSPS vs 400 MSPS). The substitution also requires verifying output interface compatibility (CMOS vs LVDS), supply voltages, and PCB pin assignments against both datasheets before validation.
What package and operating temperature range do these devices share?
Both the ADS5474IPFP and ADS5411IPGP are offered in a 100-pin HTQFP package and are specified for the industrial temperature range of -40°C to +85°C. Package sharing does not imply electrical or pin compatibility, so each device must be evaluated independently.
