MAX5381LEUK+T

The MAX5381LEUK+T is a low-cost, low-power, 8-bit digital-to-analog converter (DAC) from Analog Devices, housed in a miniature 5-pin SOT23 package. It utilizes a simple 2-wire serial interface compatible with fast-mode I2C standards, allowing data rates up to 400kbps.

This DAC features an internal +4V reference and operates over a supply voltage range of +4.5V to +5.5V. Key electrical characteristics include a maximum supply current of 230µA and a shutdown mode that reduces current to less than 1µA. The device offers ±1 LSB maximum Integral Non-Linearity (INL) and Differential Non-Linearity (DNL), with a full-scale error of less than ±5% for the MAX5382 variant.

Designed for applications such as automatic tuning, power-amplifier bias control, and programmable threshold levels, the MAX5381LEUK+T includes an output buffer capable of driving resistive loads. It also features a power-on reset function that ensures the DAC output is zero when power is initially applied. The operating temperature range is -40°C to +85°C.

The compact SOT23-5 package makes it suitable for space-constrained designs. The I2C-compatible interface minimizes board space and interconnect complexity.
