Product Introduction
The AD7699 is an 8-channel, 16-bit, charge redistribution successive approximation ADC operating from a single supply.
The AD7699 contains all the components needed for a multichannel, low power data acquisition system, including: a true 16-bit, no missing codes SAR ADC; an 8-channel, low crosstalk multiplexer for configuring inputs as single-ended (with or without a reference GND), differential, or bipolar; an internal 4.096 V low drift reference and buffer; a temperature sensor; an optional single-pole filter; and a sequencer for automatically sequencing through channels in a multichannel application.
The AD7699 uses a simple SPI to write to the configuration register and to receive conversion results. The SPI interface uses a separate supply (VIO), which sets the master logic level. Power consumption is proportional to throughput rate.
The AD7699 is housed in a 20-lead miniature LFCSP and operates over a −40°C to +85°C temperature range.
The AD7699 is an 8-channel, 16-bit, charge redistribution SAR ADC capable of converting up to 500,000 samples per second (500 kSPS) with power-down between conversions. When operating at 1 kSPS with an external reference, the typical power consumption is 52 μW, making it ideal for battery-powered applications.

- 16-bit, no missing codes SAR ADC
- 8-channel, low crosstalk multiplexer
- Internal low drift reference and buffer
- Temperature sensor with optional single-pole filter
- Channel sequencer
