The AD7657BSTZ-1 is a 14-bit successive approximation register (SAR) analog-to-digital converter from Analog Devices. It integrates six independent ADCs and supports simultaneous sampling of up to six single-ended input channels. The device operates with a 5 V supply and offers pin- and software-selectable input voltage ranges of ±10 V and ±5 V.
Key performance specifications include a throughput rate of 250 kSPS and a typical signal-to-noise ratio of 88 dB at a 10 kHz input frequency. Power dissipation is typically 140 mW at 250 kSPS. The converter features a standby mode with a maximum power consumption of 315 µW. It utilizes an internal or external reference and a 1:1 S/H-ADC ratio.
The AD7657BSTZ-1 supports multiple data interface options including SPI, parallel, and DSP-compatible modes. It is housed in a surface-mount 64-lead LQFP package (10x10 mm) and is rated for operation from -40°C to +85°C. This ADC is designed for applications requiring simultaneous data acquisition, such as power line monitoring, instrumentation, and multiaxis position control.
The supply voltage is 5 V.
It is available in a 64-lead LQFP (10x10 mm) surface-mount package.
