The AD7656BSTZ-1-RL from Analog Devices is a 6-channel, 16-bit, parallel, successive approximation, bipolar, analog-to-digital converter (ADC) integrated circuit (IC). This pin-configured IC offers a sampling rate up to 30ksps, and integrates an on-chip voltage reference and dynamic indexing logic to improve efficiency and reduce cost. The AD7656BSTZ-1-RL also includes an input multiplexer, a voltage reference, an input buffer, a channel selector and a track/hold circuit, allowing for easy interfacing. The voltage reference can be operated by an internal or external voltage. The IC’s signal conditioning circuitry includes 6 programmable gain amplifiers (PGA) that can provide gains from 1 to 8 with external resistors, while its output formats include two's complement or offset binary. With its low power consumption and small footprint, the AD7656BSTZ-1-RL is an ideal choice for applications such as process monitoring, medical instrumentation, and motor control systems.
