Data Acquisition - Analog to Digital Converters (ADC)


The ADS7861E is a dual, 12-bit, 500kSPS, Analog-to-Digital(A/D) converter with four fully differential input channelsgrouped into two pairs for high speed, simultaneous signalacquisition. Inputs to the sample-and-hold amplifiers are fullydifferential and are maintained differential to the input of theA/D converter. This provides excellent common-mode rejectionof 80dB at 50kHz which is important in high noiseenvironments.The ADS7861 offers a high-speed, dual serial interface andcontrol inputs to minimize software overhead. The output datafor each channel is available as a 12-bit word. The ADS7861is offered in both an SSOP-24 and a QFN-32 package and isfully specified over the –40°C to +125°C operating range. ADS7861E Features • 4 INPUT CHANNELS• FULLY DIFFERENTIAL INPUTS• 2μs TOTAL THROUGHPUT PER CHANNEL• NO MISSING CODES• 1MHz EFFECTIVE SAMPLING RATE• LOW POWER: 40mW• SSI SERIAL INTERFACE• OPERATING TEMPERATURE RANGE:–40°C to +125°C ADS7861E Applications • MOTOR CONTROL• MULTI-AXIS POSITIONING SYSTEMS• 3-PHASE POWER CONTROL
