This data sheet details the features and characteristics of the AD5450/AD5451/AD5452/AD5453 series of 8/10/12/14-bit high bandwidth multiplying DACs, including a 12MHz multiplying bandwidth, ±0.25LSB INL, 8-lead TSOT and MSOP packages, 2.5V to 5.5V operating voltage, ±10V reference input, 50MHz serial interface, 2.7MSPS update rate, extended temperature range (-40°C to +125°C), 4 quadrant multiplication, power-on reset and brownout detect, <0.4μA typical current consumption, and guaranteed monotonicity. This series of products is suitable for portable battery-powered applications, waveform generators, analog processing, instrumentation applications, programmable amplifiers and attenuators, digitally controlled calibration, programmable filters and oscillators, composite video, ultrasound, gain, offset, and voltage applications.
The AD5450, AD5451, AD5452, and AD5453 are CMOS multiplying digital‑to‑analog converters offering 8‑, 10‑, 12‑, and 14‑bit resolution respectively. They operate from a single 2.5 V to 5.5 V supply and accept a +10 V reference input, making them suitable for battery‑powered and automotive applications.
Key features include up to 12 MHz reference‑multiplying bandwidth, 27 MSPS update rate, extended temperature range (‑40 °C to +125 °C), and pin‑compatible packages (8‑lead TSOT, MSOP, and LFCSP). The datasheet details functional block diagrams, timing characteristics, absolute maximum ratings, and ordering information.
