MAX5156BCEE+

MAX5156BCEE+ is a 16-bit digital-to-analog converter (DAC) from Maxim Integrated (now Analog Devices). It provides a precise analog voltage output driven by a serial input (SPI-compatible) from a microcontroller or processor.
Key points:
- 16-bit resolution with monotonic, low-glitch performance.
- SPI-compatible interface: typically CS, SCLK, SDI (and LDAC for simultaneous update).
- Wide supply range and flexible reference options (external or internal) for unipolar or configured bipolar outputs.
- Output can be buffered for driving loads; suitable for precision control, calibration, and instrumentation.
- Available in RoHS-compliant package options (the BCEE+ suffix denotes packaging/grade variants).
Typical use cases: instrumentation, test equipment, process control, programmable gain/offset in embedded systems.
For exact electrical specs (input codes, VREF, output range, settling time, power consumption, temperature range, and package details), consult the latest MAX5156B datasheet and the specific BCEE+ package documentation.

I don’t have the exact datasheet visible here, but typical MAX5156BCEE+ features (common to the MAX5156 family) are:
- 16-bit resolution, dual-channel voltage-output DACs
- SPI-compatible serial interface (SCK, SDI/SDO, CS) with optional LDAC
- Buffered, rail-to-rail outputs
- Wide supply range: approx. 2.7 V to 5.5 V
- External reference input (with potential internal reference option depending on variant)
- Monotonic operation with low glitch energy and fast settling
- Power-on reset and software/hardware shutdown modes
- Industrial temperature variant available (e.g., -40°C to +85°C)
- Small package options (e.g., 8- or 16-pin)
For exact features, electrical specs, and pinout of the MAX5156BCEE+ variant you have, please refer to the specific datasheet.
