The AD7679AST is an 18-bit, 570 kSPS successive approximation register (SAR) analog-to-digital converter from Analog Devices. It offers no missing codes and no pipeline delay, making it suitable for high-precision applications.
Key specifications include an integral nonlinearity (INL) of ±2.5 LSB maximum, a typical signal-to-noise plus distortion (SINAD) of 100 dB at 2 kHz input, and a typical dynamic range of 103 dB with a 5 V reference. The device operates from a single 5 V supply and dissipates only 76 mW at 500 kSPS, with power scaling down to 150 μW at 1 kSPS.
The ADC supports differential input signals and provides flexible data interfaces including parallel (18-, 16-, or 8-bit), serial, and SPI-compatible serial. It is housed in a 48-lead LQFP package (7x7 mm) and operates over a temperature range of -40°C to +85°C. The AD7679AST is a pin-to-pin compatible upgrade of the AD7674, AD7676, and AD7678.
The AD7679AST has 18-bit resolution.
The maximum sampling rate is 570 kSPS.
The operating temperature range is -40°C to +85°C.
The AD7679AST is available in a 48-lead LQFP package (7x7 mm).
The AD7679AST is listed as RoHS compliant, but this status is unverified.
Typical power dissipation is 76 mW at 500 kSPS.
The AD7679AST supports parallel (18-, 16-, or 8-bit), serial, and SPI interfaces.
