Texas Instruments ADC0831A
The ADC0831A and ADC0831B have single input channels; the ADC0832A and ADC0832B have multiplexed twin input channels. The serial output is configured to interface with standard shift registers or microprocessors. The ADC0832 multiplexer is software configured for single-ended or differential inputs.ADC0831A, ADC0832A, ADC0831B, ADC0832B A/D PERIPHERALS WITH SERIAL CONTROL D 8-Bit Resolution D Easy Microprocessor interface or Stand-Alone Operation D Operates Ratiometrically or With 5-V Reference D Single Channel or Multiplexed Twin Channels With Single-Ended or Differential Input Options D Input Range 0 to 5 V With Single 5-V Supply D Inputs and Outputs Are Compatible With TTL and MOS D Conversion Time of 32 µs at CLK = 250 kHz D Designed to Be interchangeable With National Semiconductor ADC0831 and ADC0832 SLAS006 – AUGUST 1985 – REVISED JUNE 1986 ADC0831 . . .
