Übersicht
Description
The AD7795 operates from a single 2.7 V to 5.25 V supply and offers a programmable gain amplifier (PGA) with gains ranging from 1 to 128. This flexibility allows for the measurement of small signals directly, enhancing its applicability in various sensor applications. The device includes an on-chip clock, but also supports external clock sources for added versatility.
Communication with the AD7795 is facilitated through a simple serial peripheral interface (SPI). It also boasts features like on-chip calibration, temperature sensor, and reference options, further enhancing its usability in precision measurement tasks. The "REEL" designation indicates that the product is available in a tape and reel package, ideal for automated assembly processes.

Features
The device operates with a low power consumption, making it ideal for battery-powered applications. It includes a low-drift internal reference and an excitation current source, enhancing its performance in sensor interfacing. The AD7795 supports a serial peripheral interface (SPI) for easy integration with microcontrollers and other digital systems.
Additional features include a programmable output data rate, burnout current detection, and internal temperature sensor, providing system monitoring and diagnostics capabilities. The AD7795BRUZ-REEL is packaged in a 16-lead TSSOP, designed for compact and robust applications across industrial, healthcare, and instrumentation sectors.
Pinout
The AD7795 comes in a 16-lead TSSOP (Thin Shrink Small Outline Package), so it has 16 pins in total. The key functions of the pins include:
- Analog Inputs: Differential analog input pairs.
- Reference Inputs: Differential reference input pins.
- Serial Interface Pins: MISO, MOSI, SCLK, and CS for SPI communication.
- Power Supply Pins: AVDD (analog power supply) and DVDD (digital power supply).
- Ground Pins: AGND and DGND for analog and digital grounds.
- Clock Pin: Provides clock input for the ADC.
- Reset Pin: Allows for resetting the device.
These ADCs are commonly used in applications requiring high precision and low noise, such as weigh scales and pressure measurement systems.
