AD5428/AD5440/AD5447 are CMOS, 8-/10-/12-bit, high bandwidth, multiplying DACs with parallel interface
The AD5428, AD5440 and AD5447 are CMOS dual‑channel current‑output 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 portable, battery‑powered applications and instrumentation.
Key features include a 10 MHz multiplying bandwidth, 21.3 MSPS update rate, extended temperature range (‑40 °C to +125 °C), low typical current consumption (0.5 pA) and guaranteed monotonic performance. The devices are offered in 20‑lead (AD5428) and 24‑lead (AD5440/AD5447) TSSOP packages with full pin‑out and timing details provided.
