AD7537JRZ

The Analog Devices AD7537JRZ is a monolithic integrated circuit containing two independent 12-bit current output digital-to-analog converters (DACs) in a single package. This dual DAC design saves valuable board space and ensures excellent thermal tracking between the converters. It utilizes an R-2R architecture and supports 4-quadrant multiplication.

The AD7537JRZ offers a fast interface timing with a 2-byte loading structure, designed for right-justified data format. It accepts a wide operating voltage range of 10.8V to 16.5V and operates within an industrial temperature range of -40°C to 85°C. Key electrical specifications include a settling time of 1.5µs to 0.5 LSB and a maximum integral non-linearity (INL) of ±1 LSB.

This component is suitable for applications such as automatic test equipment, programmable filters, audio applications, synchro applications, and process control. It is available in a space-saving 24-SOIC surface mount package, measuring 7.50mm in width.

The device is manufactured using Linear Compatible CMOS (LC2MOS) process, making it speed compatible with most microprocessors and accepting TTL, 74HC, and 5V CMOS logic level inputs. It also features an asynchronous CLR line for calibration routines and double buffering for simultaneous DAC updates.
