The AD7674AST is an 18-bit, 800 kSPS successive approximation register (SAR) analog-to-digital converter (ADC) from Analog Devices. It operates from a single 5V supply and features a fully differential input with a range of ±VREF (up to 5V). The device offers three throughput modes: 800 kSPS in warp mode, 666 kSPS in normal mode, and 570 kSPS in impulse mode, allowing optimization between speed and power consumption.
Key electrical specifications include an integral nonlinearity (INL) of ±2.5 LSB maximum, a dynamic range of 103 dB typical, and a SINAD of 100 dB typical at 2 kHz. Power dissipation is 98 mW typical at 800 kSPS in warp mode, dropping to 78 mW at 500 kSPS in impulse mode, and as low as 160 µW at 1 kSPS in impulse mode. The ADC includes an internal conversion clock and reference buffer.
The AD7674AST supports multiple digital interfaces including parallel (18-, 16-, or 8-bit bus), serial, SPI, QSPI, MICROWIRE, and DSP-compatible interfaces with 5V/3V logic levels. It is housed in a 48-lead LQFP package (7x7 mm) with gull wing leads for surface mount assembly. The operating temperature range is -40°C to 85°C.
