DAC121C085 - 12-Bit Micro Power Digital-to-Analog Converter

Download the DAC121C085 datasheet PDF. This datasheet also covers the DAC121C081 variant, as both devices belong to the same 12-bit micro power digital-to-analog converter family and are provided as variant models within a single manufacturer datasheet.

Description

The DAC121C081 is a 12-bit, single-channel, voltage-output digital-to-analog converter (DAC) that operates from a 2.7-V to 5.5-V supply.

The output amplifier allows rail-to-rail output swing and has an 8.5-µs settling time.

Features

  • 1 Ensured Monotonicity to 12-Bits.
  • Low Power Operation: 156-µA Maximum at 3.3 V.
  • Extended Power Supply Range (2.7 V to 5.5 V).
  • I2C-Compatible 2-Wire Interface Which Supports Standard (100-kHz), Fast (400-kHz), and HighSpeed (3.4-MHz) Modes.
  • Rail-to-Rail Voltage Output.
  • Very Small Package.
  • Resolution: 12 bits.
  • INL: ±8 LSB (Maximum).
  • DNL: 0.6 /.
  • 0.5 LSB (Maximum).
  • Settling Time: 8.5 µs (Maximum).
