Description

MAX549ACUA+T is a Maxim Integrated digital-to-analog converter (DAC) in the MAX549 family. It’s a multi-channel, voltage-output DAC with a serial control interface (SPI-like), used to convert digital codes into precise analog voltages for instrumentation, calibration, and control systems. The “+T” indicates RoHS-compliant, lead-free packaging and tape-and-reel handling; “CUA” denotes the package and temperature grade associated with this variant.
Key points:
- Serial interface: SPI-like (SI/SCK/CS) for microcontroller compatibility
- Output: one or more voltage-output channels (exact number/resolution varies by variant)
- Supply: typically 2.7 V to about 5.5 V
- Characteristics: monotonic operation, good linearity, fast update performance
- Package: small lead-frame/flat-pack (RoHS)
For exact specs (resolution, channel count, timing), refer to the specific MAX549ACUA+T datasheet.

Pinout

- Pin count: 16 pins (16-pin package, e.g., SOIC/TSSOP).
- Function: 12-bit multiplying digital-to-analog converter (DAC) with a serial SPI-like interface (digital input to an analog output).

Manufacturer

Manufacturer: Maxim Integrated (now a wholly owned subsidiary of Analog Devices, Inc.).
What kind of company: A global semiconductor company that designs and markets analog, mixed-signal, and power-management integrated circuits.

Application

MAX549ACUA+T is a digitally controlled potentiometer. Common applications:
- Programmable gain/attenuation in op-amp feedback and instrumentation amps
- DAC/ADC references, offset and gain trimming
- Sensor signal conditioning and calibration (bridge sensors, thermistors)
- Audio volume control and tone shaping
- Programmable attenuators in RF/microwave front-ends
- Calibration/auto-calibration loops in test and instrumentation equipment
- Adjustable bias/voltage divider networks in power management and control circuits
These use cases leverage its digital wiper to set precise resistance values without mechanical pots.
