Présentation

Description

AD5541LRZ is a 12‑bit multiplying digital‑to‑analog converter (MDAC) from Analog Devices. It accepts a 12‑bit serial input (SPI‑compatible) and converts it into an output that scales a separate reference input, i.e., the digital code multiplies the reference to produce the analog result. The device provides a current output (Iout) that is typically converted to a voltage with an external precision op‑amp. It is designed for low drift, monotonic operation with low glitch, and relatively low power. Common applications include precision calibration, programmable gains/offsets, waveform generation, and instrumentation. The LRZ suffix denotes the specific package/packaging option for this part (RoHS-compliant variant).

Equivalent

AD5541LRZ is a 12-bit, serial-input multiplying DAC (SPI). There isn’t an exact one-for-one cross. Closest equivalents:
- Analog Devices: AD5540/AD5542/AD5543 (same 12-bit multiplying DAC family)
- Texas Instruments: DAC7611/DAC7612 (12-bit multiplying DACs with SPI)
Other vendors offer similar 12-bit SPI DACs. Use a distributor cross-reference (Digi‑Key/Mouser) to find exact LRZ package equivalents.

Features

AD5541LRZ is a 12‑bit multiplying DAC (MDAC) with a serial interface. Key features:
- 12-bit MDAC resolution for multiplying DAC operation (Vref sets full-scale)
- SPI-compatible serial input interface (SCLK, SDI, CS; LDAC optional for simultaneous update)
- Output as a current DAC (Iout); typically used with an external precision op-amp to obtain a voltage output
- External reference input to set full-scale range
- Low glitch and fast settling suitable for precision instrumentation
- 8‑lead package (LRZ) for RoHS-compliant, compact packaging
- Industrial temperature range (approximately -40°C to +85°C)
- Low power consumption and suitable for single-supply operation (typical 5V range in many designs)
- Applications: precision control, instrumentation, waveform generation
Note: Exact voltage ranges and pinout depend on the specific package variant; consult the datasheet for your exact part revision.

Pinout

- Pin count: 8 pins (LRZ package, SOIC-8)
- Function: 12‑bit serial-input multiplying DAC (SPI-like interface) with voltage output; converts digital code to an analog voltage using an external reference.
