Details

GENERAL DESCRIPTION The AD7788/AD7789 are low power, low noise, analog front ends for low frequency measurement applications. The AD7789 contains a low noise 24-bit ∑-∆ ADC with one differential input. The AD7788 is a 16-bit version of the AD7789. The device operates from an internal clock. Therefore, the user does not have to supply a clock source to the device. The output data rate is 16.6 Hz, which gives simultaneous 50 Hz/60 Hz rejection.FEATURES AD7788: 16-bit resolution AD7789: 24-bit resolution Power Supply: 2.5 V to 5.25 V operation Normal: 75 µA maximum Power-down: 1 µA maximum RMS noise: 1.5 µV AD7788: 16-bit p-p resolution AD7789: 19-bit p-p resolution (21.5 bits effective) Integral nonlinearity: 3.5 ppm typical Simultaneous 50 Hz and 60 Hz rejection Internal clock oscillator VDD monitor channel 10-lead MSOP

FAQs

What is AD7788?

The AD7788 is a low power, high performance, 16-bit analog-to-digital converter (ADC) designed by Analog Devices. It is suited for applications requiring high resolution, low power consumption, and precision measurement, such as portable instrumentation, industrial automation, and sensor interfaces.

How Does AD7788 Work?

The AD7788 operates by converting analog input signals into digital data with high accuracy and resolution. It features a low noise programmable gain amplifier and a precision delta-sigma ADC architecture, allowing it to achieve high precision measurements with minimal power consumption. The ADC also includes integrated filters for further noise reduction.

How Many Pins does AD7788 have and What are the Functions of the Pinout Configuration?

The AD7788 is available in a 16-lead TSSOP package. The pinout configuration includes:

DVDD, DVSS: Digital power supply and ground pins, respectively.
AVDD, AVSS: Analog power supply and ground pins, respectively.
AIN1(+), AIN1(-): Differential analog input pins for Channel 1.
AIN2(+), AIN2(-): Differential analog input pins for Channel 2.
REFIN, REFIN/2: Reference voltage input pins.
CLK, DOUT/RDY, DIN: Serial interface control pins.
RESET, PD, CS: Control and configuration pins.

What are the Pros and Cons of AD7788?

Pros:

Low Power Consumption: Operates with low power, suitable for battery-powered applications.
High Resolution: Provides 16-bit resolution for accurate measurements.
Integrated Features: Includes a programmable gain amplifier and integrated filters for noise reduction.
