Description

The TLV5628C and TLV5628I are octal 8-bit voltage output digital-to-analog converters (DACs) with buffered reference inputs (high impedance). The DACs produce an output voltage that varies between one or two times the reference voltages and GND, and the DACs are monotonic. The device is simple to use, running from a single supply of 3 to 3.6 V. A power-on reset function is incorporated to ensure repeatable start-up conditions.

Digital control of the TLV5628C and TLV5628I is over a simple 3-wire serial bus that is CMOS compatible and easily interfaced to all popular microprocessor and microcontroller devices. The 12-bit command word comprises 8 bits of data, 3 DAC select bits and a range bit, the latter allowing selection between the times 1 or times 2 output range. The DAC registers are double buffered, allowing a complete set of new values to be written to the device, then all DAC outputs are updated simultaneously through control of the LDAC terminal. The digital inputs feature Schmitt triggers for high noise immunity.

The 16-terminal small-outline D package allows digital control of analog functions in space-critical applications. The TLV5628C is characterized for operation from 0°C to 70°C. The TLV5628I is characterized for operation from -40°C to 85°C. The TLV5628C and TLV5628I do not require external trimming.
