Description
AD5142ABCPZ10-RL7 is Analog Devices’ 12‑bit multiplying digital‑to‑analog converter (MDAC) with a serial control interface. It accepts a 12‑bit digital code and a reference input to generate an analog output proportional to code × Vref (within the device’s specified range). The device features a buffered output and is designed for precise gain/offset control, programmable attenuation, calibration, and instrumentation applications. The suffixes indicate packaging: ABCPZ10 denotes the lead-frame chip-scale package (10 leads), and RL7 specifies reel/tape packaging suitable for manufacturing. For exact electrical specifications (supply voltage, interface type and timing, settling time, accuracy, and Vref range) consult the ADI datasheet.
Features
AD5142ABCPZ10-RL7 features (highlights):
- Dual 12-bit multiplying DACs with I2C serial interface
- Two independent, buffered voltage outputs
- External reference input for full-scale range (Vout scales with Vref)
- Monotonic output over full code range with low glitch energy
- I2C addressable device (standard/fast-mode compatible)
- Wide single-supply operation
- Power-on reset and/or software-controlled power-down options
- RoHS-compliant, package: PZ10, on RL7 reel (tape-and-reel)
Note: This is a concise feature snapshot; refer to the datasheet for detailed electrical specs, timing, timing diagrams, and pinout.
