1 / 12 page  TLV0831C, TLV0831I TLV0832C, TLV0832I 3-VOLT 8-BIT ANALOG-TO-DIGITAL CONVERTERS WITH SERIAL CONTROL SLAS148 – SEPTEMBER 1996 1 POST OFFICE BOX 655303 • DALLAS, TEXAS 75265 D 8-Bit Resolution D 2.7 V to 3.6 V VCC D Easy Microprocessor Interface or Standalone Operation D Operates Ratiometrically or With VCC Reference D Single Channel or Multiplexed Twin Channels With Single-Ended or Differential Input Options D Input Range 0 V to VCC With VCC Reference D Inputs and Outputs Are Compatible With TTL and MOS D Conversion Time of 32 µs at f(CLK) = 250 kHz D Designed to Be Functionally Equivalent to the National Semiconductor ADC0831 and ADC0832 at 3 V Supply D Total Unadjusted Error... ± 1 LSB description These devices are 8-bit successive-approximation analog-to-digital converters. The TLV0831 has single input channels; the TLV0832 has multiplexed twin input channels. The serial output is configured to interface with standard shift registers or microprocessors. The TLV0832 multiplexer is software configured for single-ended or differential inputs. The differential analog voltage input allows for common-mode rejection or offset of the analog zero input voltage value. In addition, the voltage reference input can be adjusted to allow encoding any smaller analog voltage span to the full 8 bits of resolution. The operation of the TLV0831 and TLV0832 devices is very similar to the more complex TLV0834 and TLV0838 devices. Ratiometric conversion can be attained by setting the REF input equal to the maximum analog input signal value, which gives the highest possible conversion resolution. Typically, REF is set equal to VCC (done internally on the TLV0832). The TLV0831C and TLV0832C are characterized for operation from 0 °C to 70°C. The TLV0831I and TLV0832I are characterized for operation from – 40 °C to 85°C.
