Description
AD5162BRMZ50 is Analog Devices’ 12-bit multiplying DAC (MDAC) with a buffered voltage output and a SPI-compatible serial interface. It converts a 12-bit digital input into a fraction of an external reference: Vout ≈ Vref × (Code/4095). The buffered output provides low impedance for immediate use in analog stages. The device is available in an 8‑pin MZ package (RoHS). Typical applications include programmable gain/offset, calibration, and sensor conditioning in instrumentation and industrial systems.
Equivalent
There isn’t an exact cross-reference for AD5162BRMZ50. Closest equivalents are dual 8‑bit digital pots with I2C and 50 kΩ end-to-end. Likely candidates: Analog Devices AD5252 (dual 8‑bit I2C pot; variants at 50k/100k). Other vendors’ options: Microchip MCP41/42 family (SPI) or MCP45xx family (I2C). For precise substitutes, please provide target interface (I2C/SPI) and end‑to‑end resistance. I can fetch exact cross-references.
