AD7799BRU - Brand New Analog Devices Analog To Digital Converters (ADCs)
-
Description
The AD7799BRU is an analog-to-digital converter (ADC) belonging to the Analog to Digital Converters (ADCs) category, designed for high precision measurement applications that require low power and low noise analog front ends. It features a low noise, 16-/24-bit ∑-∆ ADC with three differential analog inputs, allowing the direct interface of signals of small amplitude to the ADC. The AD7799BRU has a gain setting of 64, which provides an rms noise of 27 nV, while the AD7798BRU has a gain setting of 1, resulting in 40 nV rms noise when the update rate equals 4.17 Hz. The device also comes with a programmable gain, a low noise instrumentation amplifier, a low-side power switch, and programmable digital outputs.

Comparison
Advantages- The AD7799BRU is a low power and low noise device, making it ideal for high precision measurement applications.
- It has a programmable gain, a low noise instrumentation amplifier, and programmable digital outputs, making it versatile and customizable for multiple applications.
- The device has a wide power supply range of 2.7 V to 5.25 V and can operate in a temperature range of -40°C to +105°C.
Disadvantages- The AD7799BRU is only available in a 16-lead TSSOP package, which may not be suitable for all applications.
- While both the AD7798BRU and AD7799BRU have low noise, the AD7799BRU has a higher rms noise than the AD7798BRU at a gain setting of 64.
