The AD5405 is a dual 12-bit, high bandwidth, multiplying DAC with 4-quadrant resistors and a parallel interface. It has a 10 MHz multiplying bandwidth and on-chip 4-quadrant resistors that allow flexible output ranges. The INL is ±1 LSB. The AD5405 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 trimming.
The AD5405 is a CMOS, dual‑channel, 12‑bit current‑output digital‑to‑analog converter. It operates from a 2.5 V to 5.5 V supply, offers a 10 MHz multiplying bandwidth, and provides ±10 V reference inputs. The device includes on‑chip 4‑quadrant resistors for flexible output ranges and a guaranteed monotonic read‑back function.
The datasheet details pin configurations, timing characteristics, absolute maximum ratings, and typical performance graphs. It also lists applications such as portable battery‑powered devices, waveform generators, instrumentation, programmable amplifiers, and calibration systems.
