AD7738BRUZ-REEL7

AD7738BRUZ-REEL7 Description

The AD7738BRUZ-REEL7 from Analog Devices Inc. is a high-precision, 24-bit sigma-delta analog-to-digital converter (ADC) designed for demanding measurement applications. Packaged in a 28-TSSOP and supplied in tape & reel (TR), it integrates a single ADC with 4 or 8 configurable inputs, supporting both differential and single-ended signal acquisition. The device operates with a 5V analog supply and a flexible 2.7V to 3.6V or 5V digital supply, making it versatile for mixed-voltage systems. Its SPI/DSP-compatible interface ensures seamless integration with microcontrollers and digital signal processors.

AD7738BRUZ-REEL7 Features

• 24-bit resolution with 15.4kSPS sampling rate for high-accuracy data acquisition.
• True bipolar input range (±10V), enabling direct measurement of positive and negative signals without external level-shifting.
• External reference support for enhanced flexibility in precision applications.
• Low-noise performance with integrated digital filtering, ideal for industrial and instrumentation systems.
• RoHS3 compliant and REACH unaffected, meeting stringent environmental standards.
• Moisture Sensitivity Level (MSL) 1, suitable for extended storage and handling.

AD7738BRUZ-REEL7 Applications

The AD7738BRUZ-REEL7 excels in applications requiring high-resolution, low-noise signal conversion, such as:
