The AD7679AST is an 18-bit, charge redistribution SAR analog-to-digital converter (ADC) capable of a throughput of 570 kSPS. It operates on a single 5 V power supply and features a fully differential input range of ¬±VREF, with VREF supporting values up to 5 V. The device boasts a maximum integral nonlinearity (INL) of ¬±2.5 LSB and guarantees no missing codes across its 18-bit resolution. This ADC supports both serial and parallel interfaces, making it compatible with various digital systems, including SPI, QSPI, and DSP interfaces. It is designed for high-performance applications, offering a dynamic range of 103 dB and a signal-to-noise ratio (S/N+D) of 100 dB at 2 kHz. The AD7679AST is available in a 48-lead LQFP or LFCSP package and is specified for operation in a temperature range of -40¬8C to +85¬8C. Applications for the AD7679AST include medical instrumentation, high dynamic data acquisition, and sensor interfacing, making it suitable for projects requiring high accuracy and fast data conversion.
