Texas Instruments ADS7223 / ADS7263 / ADS8363 ADCs
Texas Instruments ADS7223 / ADS7263 / ADS8363 Analog-to-Digital Converters (ADCs) are ideal for a variety of applications, including motor control, power quality measurement, three-phase power control, and more. These simultaneous sampling ADCs offer two programmable reference outputs, flexible supply voltage ranges, a programmable auto-sequencer, data storage of up to four conversion results per channel, and several power-down features.
The TI ADS8363 16-bit simultaneous sampling ADC features eight pseudo or four fully differential input channels, grouped into two pairs for simultaneous signal acquisition. The analog inputs are maintained differentially to the input of the ADC. The input multiplexer can be used in either pseudo-differential mode to support up to four channels per ADC (4x2) or in fully differential mode that allows conversion of up to two inputs per ADC (2x2).
The TI ADS7263 is a 14-bit version while the ADS7223 is a 12-bit version of the ADS8363.
