AD7621ASTZ Description

Short technical summary and product information.

The AD7621ASTZ from Analog Devices is a high-performance, 16-bit, 3 MSPS charge redistribution Successive Approximation Register (SAR) Analog-to-Digital Converter (ADC). It operates from a single 2.5V power supply and offers superior linearity with no missing codes and an Integral Nonlinearity (INL) of ±2 LSB maximum.

 

Key electrical specifications include a typical Signal-to-Noise and Distortion Ratio (SINAD) of 89 dB at 100 kHz and Total Harmonic Distortion (THD) of -101 dB. The device supports multiple data interfaces including SPI, QSPI, MICROWIRE, and DSP, with both parallel (16- or 8-bit bus) and serial options. It features a 2.048V internal reference and a differential input range of ±VREF up to 2.5V.

 

Designed for applications requiring high speed data acquisition, the AD7621ASTZ is available in a 48-lead LQFP package suitable for surface mounting. Its architecture offers no pipeline delay, making it ideal for digital signal processing, instrumentation, and communications systems.
