AD7302BRU

AD7302BRU Description

The AD7302BRU from Analog Devices Inc. is an 8-bit, dual-channel digital-to-analog converter (DAC) designed for precision voltage output applications. Housed in a 20-pin TSSOP package, this surface-mount device operates with 2.7V to 5.5V analog and digital supplies, making it suitable for low-power and portable systems. The DAC utilizes a current-source architecture and features a parallel data interface for straightforward integration into digital systems. With a settling time of 2µs and ±1 LSB INL/DNL (integral/differential non-linearity), the AD7302BRU delivers high-speed, accurate analog outputs. Though now obsolete, it remains a reliable choice for legacy designs requiring stable performance.
