Its parallel data interface and external reference let you feed a 12-bit word straight from a microcontroller or FPGA bus, with the output current scaling linearly with the reference voltage. The 20-pin PDIP package (0.300\" wide, 7.62 mm) is a through-hole part that fits standard breadboards and prototyping boards — no fine-pitch soldering required. ## Linearity and monotonicity — what ±0.5 LSB INL means on the bench Integral non-linearity is specified at ±0.5 LSB maximum, and differential non-linearity at ±1 LSB maximum — this guarantees monotonicity across all 4096 codes, so the output never steps backward as the digital input increments. For a 12-bit converter with a 5 V reference, ±0.5 LSB INL corresponds to about ±1.2 mV of absolute error at the output — tight enough for most industrial set-point and trimming applications without external calibration. The 1 µs settling time to ±0.5 LSB means you can update the output at up to roughly 1 MHz word rate, though the actual throughput depends on the bus write cycle and the op-amp you use to convert the current output to a voltage. ## Supply rails and temperature range — planning the power budget The LTC7545AKN#PBF runs on dual analog/digital supplies: a 5 V logic rail and an analog supply that accepts either a single 5 V or a split 14.25 V to 15.75 V — the higher analog rail gives you more headroom for the output compliance range. The part is ROHS3 compliant, so it meets the latest EU hazardous-substance restrictions without needing a waiver.","metaTitle":"LTC7545AKN#PBF 12-Bit R-2R DAC, 1µs Settling, PDIP-20","metaDescription":"Analog Devices LTC7545AKN#PBF 12-bit multiplying DAC with R-2R architecture, 1µs settling time, parallel interface.
