AD5066 is a low power, 16-bit quad-channel, unbuffered voltage output nanoDAC offering relative accuracy, low total unadjusted error and low zero code error.
The AD5066 from Analog Devices is a 16‑bit quad‑channel unbuffered voltage output nanoDAC. It operates from a single 2.7 V to 5.5 V supply and provides high accuracy with ±1 LSB INL and low zero‑code error. The device includes individually buffered reference pins, a hardware LDAC function, programmable power‑down modes, and an asynchronous CLR for resetting outputs.
The datasheet details electrical specifications, timing characteristics, pin functions, and typical performance graphs. It also lists absolute maximum ratings, recommended supply decoupling, and mechanical dimensions for the 16‑lead TSSOP package.
