The serial input/output is configured to interface with standard shift registers or microprocessors. Detailed information on interfacing with most popular microprocessors is readily available from the factory. The TLV0834 (4-channel) and TLV0838 (8-channel) multiplexer is software-configured for single-ended or differential inputs as well as pseudodifferential input assignments. 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 of any smaller analog voltage span to the full 8 bits of resolution. The TLV0834C and TLV0838C are characterized for operation from 0 °C to 70°C. The TLV0834I and TLV0838I are characterized for operation from – 40 °C to 85°C. 1 2 3 4 5 6 7 14 13 12 11 10 9 8 NC CS CH0 CH1 CH2 CH3 DGTL GND VCC DI CLK SARS DO REF ANLG GND TLV0834 ...D OR N PACKAGE (TOP VIEW) 1 2 3 4 5 6 7 8 16 15 14 13 12 11 10 9 NC CS CH0 CH1 CH2 CH3 DGTL GND NC VCC DI CLK SARS DO REF ANLG GND NC NC – No internal connection TLV0834 . . .
