AD5424/AD5433/AD5445 is 8-/10-/12-bit, high bandwidth, multiplying DACs with parallel interface
The AD5424, AD5433, and AD5445 are CMOS current‑output digital‑to‑analog converters (DACs) offering 8‑, 10‑, and 12‑bit resolution respectively. They operate from a 2.5 V to 5.5 V supply, making them suitable for battery‑powered and portable applications. The devices feature a fast parallel interface with a 17 ns write cycle and provide data readback capability.
Key features include a 10 MHz multiplying bandwidth, +10 V reference input, extended temperature range of –40 °C to +125 °C, and low typical power consumption (0.4 µA). They are offered in 20‑lead TSSOP and 20‑lead LFCSP (chip‑scale) packages and are pin‑compatible upgrades of the AD7524/AD7533/AD7545 family.
