The MAX5381LEUK+T is a low cost, low power, 8bit DAC with 2-wire serial interface in 5 pin SOT-23 package. The MAX5381 has an internal +4V reference and operates from a +4.5V to +5.5V supply. The fast-mode I2C compatible serial interface allows communication at data rates up to 400Kbps minimizing board space and reducing interconnect complexity in many applications. The device is available with 0x60 factory preset address. It also include an output buffer, a low power shutdown mode and a power-on reset that ensures the DAC outputs are at zero when power is initially applied. In shutdown mode, supply current is reduced to less than 1μA and the output is pulled down to GND with a 10Kohm resistor. Typical applications include automatic tuning (VCO), power amplifier bias control, programmable threshold levels, automatic gain control and automatic offset adjustment.
- Less than ±1LSB max INL/DNL ensuring monotonic performance
- Operating temperature range from -40°C to 85°C
- Low glitch power-on reset to zero DAC output
- Buffered output drives resistive loads
- Low supply current is 230μA max
