The IC itself draws 3.3 mA supply current — this is the controller overhead, not the TEC load. The 1.5 A output drives small- to medium-format TECs typical in fiber-optic modules, medical laser assemblies, and industrial gas sensors. ## Package thermal path and board integration Housed in a 24-lead WFQFN with exposed pad (24-LFCSP, 4x4 mm body). The -R7 suffix indicates Tape & Reel packaging (7-inch reel, 1500 units per reel). Cut Tape (CT) is also listed for prototype or low-volume builds. This covers the full industrial ambient range (-40 to +85°C) with margin, and reaches into under-hood automotive environments where the TEC controls a lidar or infrared sensor module.","metaTitle":"ADN8834WACPZ-R7 TEC Driver, 1.5 A, 24-LFCSP","metaDescription":"ADN8834WACPZ-R7 1.5 A thermoelectric cooler driver, 2.7-5.5 V supply, -40 to +125°C.

The WACPZ-R7 is packaged in a 24-LFCSP (4x4 mm, exposed pad), while the ACBZ-R7 is in a BGA package. The LFCSP variant is easier to hand-solder and inspect, and its exposed pad provides a lower thermal resistance to the PCB ground plane."},{"question":"What compliance documentation is available for ADN8834WACPZ-R7?","answer":"The part is RoHS3 compliant (no exempted substances).
