Switching logic is synchronous to the ADC conversions, and the The maximum sample rate of the system is 1 MSPS.
GainĬonfigurations of 0.4, 0.8, 1.6, and 3.2 are available. Instrumentation amplifier (PGIA) precision analog-to-digitalĬonverter (ADC) driver for performing the single-ended toĭifferential conversion and an 18-bit, 1 MSPS PulSAR ® ADCįor sampling the signal on the active channel. The analog front end includes a multiplexer, programmable gain The circuit can process eight gain-independent channels and isĬompatible with both single-ended and differential input signals. Multichannel Data Acquisition Simplified Circuit (All Connections and Decoupling Not Shown) Performance at channel switching rates up to approximatelyħ50 kHz. To optimize settling time between samples, providing 18-bit
The circuit shown in Figure 1 is a cost effective, low power, multichannelĭata acquisition system that is compatible with standard
