Overview

The AD7750 is a Product-to-Frequency Converter (PFC) that can be configured for power measurement or voltage-to-frequency conversion. The part contains the equivalent of two channels of A/D conversion, a multiplier, a digital-to-frequency converter, a reference and other conditioning circuitry. Channel 1 has a differential gain amplifier with selectable gains of 1 or 16. Channel 2 has a differential gain amplifier with a gain of 2. A high-pass filter can be switched into the signal path of Channel 1 to remove any offsets. The most popular use of this general purpose integrated circuit is for solid state energy meters.

PLEASE NOTE: The AD7750 is not recommended for new designs. Please review our ADE7755 product for your application requirements.
