Low-Cost, +5V, Serial-Input, Voltage-Output, 16-Bit DAC
General Description
The MAX5541 serial-input, voltage-output, 16-bit monotonic digital-to-analog converter (DAC) operates from a single +5V supply. The DAC output is unbuffered, resulting in a low 0.3mA supply current and low 1LSB offset error. The DAC output range is 0V to VREF. The DAC latch accepts a 16-bit serial word. A power-on reset ( P O R ) circuit clears the DAC output to 0V (unipolar mode) when power is initially applied. T h e 10MHz 3-wire serial interface is SPITM/QSPITM/ MICROWIRETM-compatible and interfaces directly with optocouplers for applications requiring isolation. The MAX5541 is available in an 8-pin SO package. For the 1LSB (max) INL version, refer to the MAX541 data sheet. o +5V Single-Supply Operation o Low Power: 1.5mW o 1µs Settling Time o Unbuffered Voltage Output Directly Drives 60k Loads o SPI/QSPI/MICROWIRE-Compatible Serial Interface o Power-On Reset Circuit Clears DAC Output to 0V (unipolar mode) o Schmitt Trigger Inputs for Direct Optocoupler Interface o Choose MAX541 as a 1LSB (max) INL Upgrade to the MAX5541

Stresses beyond those listed under "Absolute Maximum Ratings" may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.

Refer to the MAX541 for the 1LSB (max) INL version. Gain error tested at VREF = +2.0V, +2.5V, and +3.0V. ROUT tolerance is typically ±20%. Min/max ranges guaranteed by gain-error test. Operation outside min/max limits will result in degraded performance. Reference input resistance is code dependent, minimum at 8555 hex. Slew-rate value is measured from 0% to 63%. Guaranteed by design. Not production tested.
