AD5344BRU

AD5344BRU Description

The AD5344BRU from Analog Devices Inc. is a 12-bit, quad-channel digital-to-analog converter (DAC) with voltage output, housed in a 28-TSSOP package. Designed for precision applications, it features a parallel data interface and operates with dual supply voltages (2.5V to 5.5V for both analog and digital domains). The device utilizes a string DAC architecture, ensuring high linearity with ±2 LSB INL and ±0.2 LSB DNL errors. With a 10µs settling time, it delivers fast and stable output transitions. The external reference requirement allows flexibility in setting the output range. Though marked obsolete, it remains a reliable choice for legacy systems requiring multi-channel DAC performance.

AD5344BRU Features

• 12-bit resolution with 4 independent DAC channels for multi-channel systems.
• Low INL/DNL errors (±2 LSB INL, ±0.2 LSB DNL) ensuring high accuracy.
• Wide supply range (2.5V–5.5V) compatible with mixed-voltage systems.
• Parallel interface for straightforward integration with microcontrollers or FPGAs.
