Analog Devices AD7667 16‑Bit 1 MSPS PulSAR® Unipolar ADC Datasheet
The AD7667 is a 16‑bit, 1 MSPS PulSAR® unipolar ADC that operates from a single 5 V supply. It includes an internal 2.5 V reference, error‑correction circuitry, and supports both parallel and serial (SPI/QSPI/MICROWIRE/DSP compatible) interfaces.
Key features include three throughput modes (Warp 1 MSPS, Normal 800 kSPS, Impulse 666 kSPS), low power dissipation (as low as 130 µW at 1 kSPS), and a specified operating temperature range of –40 °C to +85 °C.

What is the maximum sampling rate of the AD7667?
The AD7667 can sample at up to 1 MSPS in Warp mode, 800 kSPS in Normal mode, and 666 kSPS in Impulse mode.
How does power consumption change in Impulse mode?
In Impulse mode the power dissipation decreases with throughput, roughly proportional to the sampling rate.
