description
The TLV5620C and TLV5620I are quadruple 8-bit voltage output digital-to-analog converters (DACs) with
buffered reference inputs (high impedance). The DACs produce an output voltage that ranges between either
one or two times the reference voltages and GND; and, the DACs are monotonic. The device is simple to use,
because it runs from a single supply of 3 V to 3.6 V. A power-on reset function is incorporated to ensure
repeatable start-up conditions.
Digital control of the TLV5620C and TLV5620I is over a simple three-wire serial bus that is CMOS compatible
and easily interfaced to all popular microprocessor and microcontroller devices. The 11-bit command word
comprises eight bits of data, two 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 update simultaneously through control of LDAC. The digital inputs
feature Schmitt triggers for high noise immunity.
The 14-terminal small-outline (SO) package allows digital control of analog functions in space-critical
applications. The TLV5620C is characterized for operation from 0°C to 70°C. The TLV5620I is characterized
for operation from – 40°C to 85°C. The TLV5620C and TLV5620I do not require external trimming.

DESCRIPTION
I Serial interface clock. The input digital data is shifted into the serial interface register on the falling edge of the clock
applied to the CLK terminal.
O DAC A analog output
O DAC B analog output
O DAC C analog output
O DAC D analog output
I Serial interface digital data input. The digital code for the DAC is clocked into the serial interface register serially.
Each data bit is clocked into the register on the falling edge of the clock signal.
I Ground return and reference terminal
I Load DAC. When this signal is high, no DAC output updates occur when the input digital data is read into the serial
interface. The DAC outputs are only updated when LDAC is taken from high to low.
I Serial interface load control. When the LDAC terminal is low, the falling edge of the LOAD signal latches the digital
data into the output latch and immediately produces the analog voltage at the DAC output terminal.
I Reference voltage input to DAC A. This voltage defines the output analog range.
I Reference voltage input to DAC B. This voltage defines the analog output range.
I Reference voltage input to DAC C. This voltage defines the analog output range.
I Reference voltage input to DAC D. This voltage defines the analog output range.
I Positive supply voltage
