Product details

12-bit SAR ADC in a SOT-23-8 package

It accepts a single pseudo-differential input and communicates over an SPI or DSP-compatible serial interface. The part operates from a single 2.7 V to 5.25 V supply and is housed in an 8-lead SOT-23-8 package, making it a fit for space-constrained, low-power instrumentation, data acquisition, and industrial control applications where 12-bit resolution at moderate speed is sufficient.

For dual-sourcing or a higher-resolution alternative, the AD7683ACPZRL7 (16-bit, same pin-compatible footprint and serial interface) is a functional second source if your system can use the extra two bits at the same 100k sample rate.

Frequently asked questions

What is the recommended alternative if AD7457BRTZ-REEL7 is not available?

The AD7683ACPZRL7 is a pin-compatible 16-bit SAR ADC with the same 100k sample rate, pseudo-differential input, and SPI interface — a direct resolution upgrade that fits the same SOT-23-8 footprint.
