The AD5300 is an 8-bit DAC with a power supply range of 2.7 V to 5.5 V, operating current of 140 μA, and Rail-to-Rail output. It is available in SOT-23 package and features low power operation, single-chip design, power supply compensation, etc. It is suitable for portable battery-powered instruments, digital gain and offset adjustment, programmable voltage and current sources, programmable attenuators, and other applications.
The AD5300 is a single‑channel 8‑bit DAC that operates from a single 2.7 V to 5.5 V supply. It features an on‑chip precision output buffer that provides rail‑to‑rail voltage swing and a low‑power serial interface compatible with SPI, QSPI, MICROWIRE and DSP standards.
Key features include micropower operation (115 µA at 3 V, 140 µA at 5 V), power‑down current as low as 50 nA, a 1 V/µs slew rate, and a maximum serial clock frequency of 30 MHz. The device is offered in 6‑lead SOT‑23 and 8‑lead MSOP packages and is qualified for automotive use.
