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
The TLV5620C and TLV56201 are quadruple 8‑bit voltage‑output DACs that operate from a single 3 V to 3.6 V supply. They provide buffered reference inputs, selectable 1× or 2× output range, and a three‑wire serial interface compatible with common microcontrollers.
The device is offered in a 14‑pin small‑outline (SO) package and a 16‑pin plastic dual‑in‑line (PDIP) package, with operating temperature ranges of 0 °C‑70 °C for the TLV5620C and –40 °C‑85 °C for the TLV56201. Detailed electrical characteristics, timing diagrams, and mechanical dimensions are included.
| Supply voltage Vpp (min‑typ‑max) | 2.7 V – 3.3 V – 5.25 V |
|---|---|
| Supply current (IDD) typical | 2 mA at Vpp = 3.3 V |
| Maximum clock frequency | 1 MHz |
| Output source current (typ) | 1 mA |
The output can swing between the reference voltage and ground, or up to twice the reference voltage when the range bit is set.
The TLV5620 contains four independent DAC channels, making it a quadruple DAC.
