The AD7606C-16 is a 16-bit, simultaneous sampling, analog-to-digital data acquisition system (DAS) with eight channels. Each channel contains analog input clamp protection, a programmable gain amplifier (PGA), a low-pass filter (LPF), and a 16-bit successive approximation register (SAR) analog-to-digital converter (ADC). The AD7606C-16 also contains a flexible digital filter, a low drift, 2.5 V precision reference, a reference buffer to drive the ADC, and flexible parallel and serial interfaces. The AD7606C-16 operates from a single 5 V supply and accommodates the following input ranges when sampling at throughput rates of 1 MSPS for all channels:
- Bipolar single-ended: ±12.5 V, ±10 V, ±6.25 V, ±5 V, and±2.5 V
- Unipolar single-ended: 0 V to 12.5 V, 0 V to 10 V, and 0 V to 5 V
- Bipolar differential: ±20 V, ±12.5 V, ±10 V, and ±5 V
The input clamp protection tolerates voltages up to ±21 V. The single supply operation, on-chip filtering, and high input impedance eliminate the need for external driver op amps, which require bipolar supplies. For applications with lower throughput rates, the AD7606C-16 flexible digital filter can be used to improve noise performance. In hardware mode, the AD7606C-16 is fully compatible with the AD7606 and AD7606B. In software mode, the following advanced features are available:
- Analog input range selectable per channel with added ranges available
- High bandwidth mode (220 kHz) selectable per channel
- Additional oversampling options with an oversampling ratio up to 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 and write, cyclic redundancy check (CRC), busy stuck monitor, and reset detection)
Note that throughout this data sheet, multifunction pins, such as the RD/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.
