It accepts parallel digital input data and settles to within 0.5 LSB in 2 µs typical. The reference type is external, and the analog and digital supply rails share a common 4.75 V to 15.25 V range — a single supply rail can power both sides, simplifying the board-level power distribution. Housed in a 20-lead PLCC (J-Lead) package with a 9x9 mm body, the device is intended for surface-mount assembly. ## Linearity and settling performance Integral non-linearity is ±0.5 LSB maximum, and differential non-linearity is ±1 LSB maximum — the INL spec means the transfer function stays within half an LSB of an ideal straight line across all 4096 codes, which is tight enough for most 12-bit control-loop and waveform-generation applications without software calibration. The 2 µs settling time to ±0.5 LSB sets the maximum update rate at roughly 500 kHz for a full-scale step. For smaller code changes the settling is faster, but the parallel interface itself can accept data at a higher rate than the DAC can settle — the host must insert wait states or use a handshake if the application requires code-to-code updates faster than the settling window. ## Lifecycle and compliance reality RoHS compliance is not claimed for this order code — the part is marked RoHS non-compliant. Buyers with RoHS-required BOM lines should verify the exemption or plan for a leaded-process assembly step. ## Sourcing and cross-reference fit The AD7545LP is sourced to order through independent distribution channels. The key difference is package and supply format: the AD7545LP comes in a 20-PLCC (J-Lead) in bulk tubes, while the AD7545AKRZ-REEL7 is a 20-SOIC wide-body on tape-and-reel. The PLCC footprint does not drop into a SOIC land pattern — a board layout change is required to swap between them.","metaTitle":"AD7545LP 12-bit Multiplying DAC, PLCC-20, Parallel Input","metaDescription":"AD7545LP 12-bit multiplying DAC, R-2R architecture, 2µs settling, parallel interface, 20-PLCC.
