Product Details
The AD5384 is a complete single-supply, 40-channel, 14-bit digital-to-analog converter (DAC) available in a 100-ball CSP_BGA package. All 40 channels have an on-chip output amplifier with rail-to-rail operation. The AD5384 includes an internal 1.25 V/2.5 V, 10 ppm/°C reference, an on-chip channel monitor function that multiplexes the analog outputs to a common MON_OUT pin for external monitoring, and an output amplifier boost mode that allows the amplifier slew rate to be optimized. The AD5384 contains a serial interface compatible with SPI, QSPI, MICROWIRE, and DSP interface standards with interface speeds in excess of 30 MHz and an I2C-compatible interface supporting 400 kHz data transfer rate. An input register followed by a DAC register provides double buffering, allowing the DAC outputs to be updated independently or simultaneously, using the LDAC input. Each channel has a programmable gain and offset adjust register letting the user fully calibrate any DAC channel. Power consumption is typically 0.25 mA per channel with boost mode off.
APPLICATIONS
- Variable optical attenuators (VOAs)

Precision DAC Error Budget Tool
The Precision DAC Error Budget Tool is a web application that calculates the DC Accuracy of precision DAC signal chains. It shows how the static errors accumulate throughout your signal chain to quickly evaluate the design tradeoffs. Calculations include the DC errors introduced by Voltage References, Operation Amplifiers and Precision DACs.
