Product details

Supply range and reference — no external reference needed

The reference type is Supply, using the analog supply voltage as reference. This eliminates an external reference IC.

Interface and throughput — SPI/DSP at 200k SPS

The serial interface is compatible with SPI and DSP controllers. At 200k samples per second, the conversion time and data transfer fit comfortably within the timing of most MCU SPI peripherals running at a few MHz. The single-ended input with a 1:1 S/H-to-ADC ratio means one sample-and-hold feeds the converter directly — no input mux, no channel scan. For applications that only need one analog channel, this keeps the firmware simple.

The SOT-23-6 package is surface-mount and suitable for standard reflow soldering.

Frequently asked questions

Are there equivalent or alternative parts to AD7466BRTZ-R2?

The AD7467BRMZ is a 10-bit pin-compatible sibling in the same family, same 200k SPS rate and SOT-23 footprint, but with 10-bit resolution instead of 12-bit. The AD7910 is another 10-bit SAR ADC at 250k SPS, but in a different package (SC-70). For a drop-in 12-bit replacement, the AD7466BRTZ-R2 itself is the target; no exact 12-bit second-source is listed.
