12.4. TSH22
12.4.1. General Description
The TSH22 is a dual bipolar operational amplifier offering a single supply operation from 3V to 30V with
very good performances: medium speed (25MHz), unity gain stability and low noise.
The TSH 22 is therefore an enhanced replacement of standard dual operational amplifiers.

12.5. CS4334
12.5.1. General Description
The CS4334 family members are complete, stereo digital-to-analogue output systems including
interpolation, 1-bit D/A conversion and output analogue filtering in an 8-pin package. The CS4334/5/6/7/8/9
support all major audio data interface formats and the individual devices differ only in the supported
interface format.
The CS4334 family is based on delta-sigma modulation, where the modulator output controls the reference
voltage input to an ultra-linear analogue low-pass filter. This architecture allows for infinite adjustment of
sample rate between 2 kHz and 100 kHz simply by changing the master clock frequency.
The CS4334 family contains on-chip digital de-emphasis, operates from a 5V power supply, and
requires minimal support circuitry. These features are ideal for portable CD players and other portable
playback systems.
