Texas Instruments ADC08831IWM

ADC, Successive Approximation, 8-Bit, 1 Func, 1 Channel, Serial Access, CMOS, PDSO14

The ADC08831/ADC08832 are 8-bit successive approxima-tion Analog to Digital converters with 3-wire serial interfaces and a configurable input multiplexer for 2 channels. The se-rial I/O will interface to COPS (TM)family of micro-controllers, Pl D's, microprocessors, DSP's, or shift registers. The serialI/O is configured to comply with the NSC MICRO WIRE (TM) serial data exchange standard. To minimize total power consumption, theADC08831/ADC08832 automatically go into low power mode whenever they are not performing conversions. A track/hold function allows the analog voltage at the positive input to vary during the actual A/D conversion. The analog inputs can be configured to operate in various combinations of single-ended, differential, or pseudo-differential modes. The voltage reference input canbe adjusted to allow encoding of small analog voltage spans to the full 8-bits of resolution.
