LINEAR INTEGRATED CIRCUIT
rectifier and DG cell, and a bias current for the DG cell. The low tempco of this type of reference provides very
stable biasing over a wide temperature range.
The typical performance characteristics illustration shows the basic input-output transfer curve for basic
compressor or expander circuits.
