AD7710 . FEATURES. Charge Balancing ADC. 24 Bits, No Missing Codes. 0.0015% Nonlinearity. 2-Channel Programmable Gain Front End. Gains from 1 to 128. This application note describes the evaluation board for the AD7710 24-bit, signal conditioning A/D converter. This converter utilizes sigma-delta techniques to AD7719, AD7714, AD7730, AD7710 . Weighscale. Requirements: Low level differential analog inputs with a high level differential reference input for ratiometric Figure 2 shows the AD7710 used in a thermocouple application. The sensor is connected to AIN1 which includes a burn-out detector current source. When this. The AD7710 , AD7711, AD7712, and. AD7713 are the rst members of a family of sigma-delta converters de- signed for high accuracy, low frequency.
