GP520A Datasheet (Gennum) - Programmable Analog Signal Processor

GP520A, Programmable Analog Signal Processor

The GP520A is a programmable analog signal path IC designed for use in hearing instruments.

The GP520A’s programmable parameters are adjusted by external programming currents, such as generated by the GP521.

The GP520A provides a 2.5 µ A reference current for use by the GP521.

Sixteen settings are p
