Description

The AD7606B is a 16-bit, simultaneous sampling, analog-to-digital data acquisition system (DAS) with eight channels, each channel containing analog input clamp protection, a programable gain amplifier (PGA), a low-pass filter, and a 16-bit successive approximation register (SAR), analog-to-digital converter (ADC). The AD7606B also contains a flexible digital filter, low drift, 2.5 V precision reference and reference buffer to drive the ADC and flexible parallel and serial interfaces.The AD7606B operates from a single 5 V supply and accommodates ±10 V, ±5 V, and ±2.5 V true bipolar input ranges when sampling at throughput rates of 800 kSPS for all channels. The input clamp protection tolerates voltages up to ±21 V. The AD7606B has a 5 MΩ analog input impedance, resulting in less than 20 LSB bipolar zero code when the input signal is disconnected and pulled to ground through a 10 kΩ external resistor. The single supply operation, on-chip filtering, and high input impedance eliminates the need for external driver op amps, which require bipolar supplies. For applications with lower throughput rates, the AD7606B flexible digital filter can be used to improve noise performance.In hardware mode, the AD7606B 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.System gain, system offset, and system phase calibration per channel.Analog input open circuit detector.Diagnostic multiplexer.Monitoring functions (serial peripheral interface (SPI) invalid read/write, cyclic redundancy check (CRC), overvoltage and undervoltage events, busy stuck monitor, and reset detection).Note that throughout this data sheet, multifunction pins, such as theRD/SCLK pin, are referred to either by the entire pin name or by a single function of the pin, for example, the SCLK pin, when only that function is relevant.ApplicationsPower line monitoringProtective relaysMultiphase motor controlInstrumentation and control systemsData acquisition systems
