AD5425

Data Sheet 8-Bit, High Bandwidth Multiplying DAC with Serial Interface AD5425 FEATURES GENERAL DESCRIPTION 2.5 V to 5.5 V supply operation 50 MHz serial interface 2.47 MSPS update rate INL of ±0.25 LSB 10 MHz multiplying bandwidth ±10 V reference input Low glitch energy: <2 nV-s The AD54251 is a CMOS, 8-bit, current output digital-to-analog converter (DAC) that operates from a 2.5 V to 5.5 V power supply, making it suitable for battery-powered applications and many other applications. This DAC utilizes a double buffered, 3-wire serial interface that is compatible with SPI®, QSPI™, MICROWIRE™, and most DSP Extended temperature range: −40°C to +125°C interface standards. An LDAC pin is also provided, which 10-lead MSOP package Guaranteed monotonic 4-quadrant multiplication Power-on reset with brownout detection LDAC function 0.4 µA typical power consumption APPLICATIONS allows simultaneous updates in a multiDAC configuration. On power-up, the internal shift register and latches are filled with 0s and the DAC outputs are 0 V. As a result of manufacturing on a CMOS submicron process, this DAC offers excellent 4-quadrant multiplication characteristics with large signal multiplying bandwidths of 10 MHz. Portable battery-powered applications Waveform generators The applied external reference input voltage (VREF) determines the full-scale output current. An integrated feedback resistor, Analog processing RFB, provides temperature tracking and full-scale voltage output I...
