Product Introduction
The AD7606B is a 16-bit, simultaneous sampling, analog-to-digital data acquisition system (DAS) with 8 channels, each featuring built-in analog input clamp protection, a programmable gain amplifier (PGA), a low-pass filter, and a 16-bit successive approximation register (SAR) ADC. It also integrates a flexible digital filter, a low-drift 2.5 V precision voltage reference, a reference buffer (for driving the ADC), and flexible parallel and serial interfaces.
Powered by a single 5 V supply, it supports ±10 V, ±5 V, and ±2.5 V true bipolar input ranges when all channels are sampled at a throughput rate of 800 kSPS. The input clamp protection can withstand voltages up to ±21 V. With a 5 MΩ analog input impedance, the bipolar zero code is less than 20 LSB when the input signal is disconnected and pulled to ground through a 10 kΩ external resistor. Single-supply operation, on-chip filtering, and high input impedance eliminate the need for external driver op-amps (which require bipolar supplies). For lower throughput applications, the flexible digital filter can be used to improve noise performance.
In hardware mode, it is fully compatible with the AD7606. In software mode, the following advanced features are available:
- Additional ±2.5 V analog input range.
- Analog input range (±10 V, ±5 V, and ±2.5 V) selectable per channel.
- Additional oversampling (OS) options, up to OS×256.
- Per-channel system gain, system offset, and system phase calibration. Analog input open-circuit detector.
- Diagnostic multiplexer.
- Monitoring functions (SPI invalid read/write, CRC, overvoltage and undervoltage events, busy blocking monitor, and reset detection).
