It integrates the current-setting switches on-chip, so no external MOSFETs are needed per channel — just the LED strings and a current-set resistor. The driver accepts a wide input supply from 3 V up to 30 V, which covers automotive battery rails, industrial 24 V buses, and standard 5 V or 12 V logic supplies. Dimming is handled either by an analog control voltage or by a PWM signal, giving the firmware engineer flexibility to trade off color temperature against brightness linearity. The operating temperature range is -40°C to 105°C. ## 500 mA per channel — thermal and current-matching budget Each of the four outputs is rated for 500 mA continuous. The linear topology dissipates heat as the voltage drop across the pass element. ## Active lifecycle — no LTB risk The ADP8140ACPZ-2-R7 carries an Active product status from Analog Devices. The part is also ROHS3 compliant, so it meets the current EU restriction-hazardous-substances directive without exemption. ## Pin-compatible sibling — ADP8140ACPZ-1-R7 The closest functional second-source is the ADP8140ACPZ-1-R7. Both are linear LED drivers in the same 16-LFCSP package with the same 4-output, 500 mA per-channel architecture, the same 3 V to 30 V supply range, and the same analog-plus-PWM dimming capability. The -1 and -2 suffix likely denotes a factory-programmed current-set or a minor trim variant — the datasheet should confirm whether the external resistor value differs. For dual-sourcing or a drop-in alternate during allocation, the -1 variant is the first candidate to qualify.","metaTitle":"ADP8140ACPZ-2-R7 Linear LED Driver, 4-Ch 500 mA, 16-LFCSP","metaDescription":"ADI ADP8140ACPZ-2-R7 linear LED driver with 4 outputs at 500 mA each.
