Features & Applications
The TS472IQT is a differential-input microphone preamplifier optimized for high-performance PDA and notebook audio systems.
This device features an adjustable gain from 0 to 40 dB with excellent power-supply and commonmode rejection ratios. In addition, the TS472 has a very low noise microphone bias generator of 2 V.
Features:
- Low noise: 10 nV/vHz typ. equivalent input noise at F = 1 kHz
- Fully-differential input/output
- 2.2 to 5.5 V single supply operation
- Low power consumption at 20 dB: 1.8 mA
- Fast start up time at 0 dB: 5 ms typ.
- Low distortion: 0.1% typ.
- 40 kHz bandwidth regardless of the gain
- Active low standby mode function (1 µA max)
- Low noise 2.0 V microphone bias output
- Available in flip-chip lead-free package and in QFN24 4 x 4 mm package
- ESD protection (2 kV)
Applications:
- Video and photo cameras with sound input
