20 / 66 page  6 Detailed Description 6.1 Overview The ADS9813 is an 18-bit data acquisition (DAQ) system with eight analog input channels configurable as either single-ended or differential. Each analog input channel consists of an input clamp protection circuit and a programmable gain amplifier (PGA) with user-selectable bandwidth options. The input signals are digitized with an 18-bit analog-to-digital converter (ADC), based on the successive approximation register (SAR) architecture. This overall system achieves a maximum throughput of 2MSPS per channel for all channels. The device has a 4.096V internal reference with several features that provide communication with a wide variety of digital hosts. These features include a fast-settling buffer, a programmable digital averaging filter to improve noise performance, and a high-speed data interface. The device operates from 5V and 1.8V analog supplies and accommodates true bipolar input signals. The input clamp protection circuitry tolerates voltages up to ±18V. The device offers a constant 1MΩ resistive input impedance irrespective of the sampling frequency or the selected input range. The ADS9813 offers a simplified end solution without requiring external high-voltage bipolar supplies and complicated driver circuits. 6.2 Functional Block Diagram SMPL_CLK 4.096 V VREF GND AVDD_5V D1 D2 D3 SMPL_SYNC CS SCLK SDI / EXTREF SDO Digital logic and Data Interface Con gura on Registers VDD_1V8 IOVDD RESET D0 REFIO ADC REF 2.5 V REFOUT_2V5 FCLKOUT DCLKOUT SPI_EN REFM PWDN Clamp AIN1P AIN1M 1M 1M Prog.
