AD7767 is an Analog Devices 24-bit, 8.5 mW, 109 dB, 128/64/32 kSPS ADC with high performance AC and DC accuracy and low power consumption.
The AD7767, AD7767‑1 and AD7767‑2 are high‑performance 24‑bit oversampled SAR analog‑to‑digital converters. They deliver dynamic ranges from 108 dB to 115.5 dB while consuming only 8.5 mW to 15 mW, depending on the output data rate, and are supplied in a 16‑lead TSSOP package.
Key features include an on‑chip FIR low‑pass filter with linear phase response, daisy‑chain capability, a SYNC/PD pin for synchronization and power‑down, and operation over a wide temperature range (‑40 °C to +105 °C). The device supports flexible serial interfaces and provides precise DC accuracy with no missing codes.
