Description

The GM0936TQ contains A/D and D/A conversion functions integrated on a single chip, and utilizes the sigma-delta modulation technique to achieve high resolution data conversion and low power consumption. The GM0936TQ is an ideal analog front end device for high performance voice-band communication systems. Cellular telephone systems are targeted in particular; however, these integrated circuits can function in other systems including digital audio, telecommunications, and data acquisition.
