Replacement verdict
Compatible functional replacement candidate
The AD5452YRMZ and AD5453YRM are functionally compatible 12-bit and 14-bit multiplying DACs in the same MSOP-8 package with identical pinout and reference input architecture. The AD5453YRM offers higher resolution, making it a viable upgrade path where the system can accommodate the increased resolution and updated digital interface timing. Designers should validate the digital interface timing and reference voltage headroom before substituting.

Key electrical and mechanical differences between the two devices
| Parameter | AD5452YRMZ | AD5453YRM | Why it matters |
|---|---|---|---|
| Resolution | 12 bits | 14 bits | Resolution determines the smallest output step and overall precision; a 14-bit DAC provides four times finer granularity than a 12-bit DAC, so the two are not functionally equivalent in accuracy-critical designs. |
| Number of DAC Channels | 1 | 1 | Both are single-channel multiplying DACs, so channel count is not a differentiator for substitutability. |
| Interface Type | SPI-compatible serial | SPI-compatible serial | A matching serial interface allows the same microcontroller or FPGA firmware to drive either device without protocol changes. |
| Supply Voltage (VDD) | 2.5 V to 5.5 V | 2.5 V to 5.5 V | Identical supply ranges mean either part can operate in the same power rail configuration, simplifying board-level substitution. |
| Reference Input Range | ±10 V (multiplying) | ±10 V (multiplying) | Both accept a wide bipolar reference, enabling four-quadrant multiplication; matching this range preserves analog signal scaling behavior. |
| INL (Integral Nonlinearity) | ±0.5 LSB typical | ±1 LSB typical | INL defines deviation from an ideal transfer curve; the tighter INL of the 12-bit part can matter in precision applications even though its resolution is lower. |
| Package | 10-lead MSOP | 10-lead MSOP | Identical package and pinout allow a drop-in footprint replacement without PCB redesign. |
| Operating Temperature Range | -40 °C to +125 °C | -40 °C to +125 °C | Matching industrial temperature ranges ensure both parts are suitable for the same environmental conditions. |
| Settling Time | 100 ns typical | 100 ns typical | Equivalent settling time means dynamic performance in waveform generation or control loops is comparable between the two devices. |

Frequently asked questions
What are the key differences between the AD5452YRMZ and AD5453YRM?
The AD5452YRMZ is a 12-bit multiplying DAC, while the AD5453YRM is a 14-bit multiplying DAC. Both are members of the Analog Devices AD545x family and share the same 8-lead MSOP package, serial interface, and multiplying bandwidth characteristics, but they differ in resolution and therefore in INL, DNL, and gain error specifications.
Are the AD5452YRMZ and AD5453YRM pin-compatible?
Yes. Both devices are offered in the same 8-lead MSOP (RM) package and share an identical pinout, including VDD, VREF, RFB, IOUT, AGND, DGND, SYNC, and SCLK functions. This allows a common PCB footprint, but resolution-dependent performance differences must still be evaluated.
What is the resolution of each device?
The AD5452YRMZ provides 12-bit resolution (4096 codes), and the AD5453YRM provides 14-bit resolution (16384 codes). The higher resolution of the AD5453YRM yields finer output steps for a given reference voltage.
Do both parts use the same digital interface?
Yes. Both the AD5452YRMZ and AD5453YRM use a 3-wire serial interface compatible with SPI, QSPI, MICROWIRE, and DSP interface standards. Data is clocked into the shift register on the falling edge of SCLK and transferred to the DAC register on the rising edge of SYNC.
What is the supply voltage range for these DACs?
Both the AD5452YRMZ and AD5453YRM operate from a single 2.5 V to 5.5 V supply. The digital inputs are compatible with 3 V and 5 V logic levels, allowing direct interfacing with common microcontrollers and DSPs.
Can the AD5452YRMZ be replaced by the AD5453YRM in an existing design?
Because the AD5453YRM has 14-bit resolution versus 12-bit for the AD5452YRMZ, the digital code-to-output transfer function differs. A direct drop-in replacement is not recommended unless the system firmware and analog output scaling are updated to account for the higher resolution and the associated INL, DNL, and gain error specifications.
What are the reference input and multiplying bandwidth characteristics?
Both devices are multiplying DACs that accept an AC or DC reference input at VREF. They feature a multiplying bandwidth of 12 MHz typical and a 4-quadrant multiplication capability, allowing the reference input to be a bipolar signal for applications such as waveform generation and programmable attenuation.
What are the operating temperature ranges for these devices?
Both the AD5452YRMZ and AD5453YRM are specified for the industrial temperature range of −40°C to +125°C, making them suitable for industrial, instrumentation, and automotive-adjacent applications where wide temperature operation is required.
