ICL7106 datasheet

 

Description

The Intersil ICL7106 and ICL7107 are high performance, low power, 3 1/2 digit A/D converters. Included are seven segment decoders, display drivers, a reference, and a clock.

The ICL7106 is designed to interface with a liquid crystal display (LCD) and includes a multiplexed backplane drive; the ICL7107 will directly drive an instrument size light emitting diode (LED) display.

Features

1. Guaranteed zero reading for 0V input on all scales
2. True polarity at zero for precise null detection
3. 1pA typical input current
4. On-chip clock and reference
5. Low power dissipation – typically less than 10mW
6. No additional active circuits required
7. Enhanced display stability

AAT1171 datasheet

 

Description

The AAT1171 SwitchReg™ dynamically controls the operating voltage of a WCDMA or CDMA power amplifier inside single-cell, lithium-ion battery-powered systems. The AAT1171 outputs a voltage between 0.6V and 3.6V, thereby optimizing the amplifier efficiency at both low and high transmit levels.

The AAT1171 output voltage is controlled via an analog signal from the baseband processor. It can deliver
600mA of continuous load current while maintaining a low 45μA of no load quiescent current. The 2MHz switching frequency minimizes the size of external components while keeping switching losses low. To further improve system efficiency, an 85mΩ bypass MOSFET transistor is also included to allow the PA to be powered directly from the battery.

Features

1. VIN Range : 2.7V to 5.5V
2. Variable Output Voltage : 0.6V to 3.6V
3. 600mA Output Current
4. DAC Input: 0.2V to 1.2V
5. High Output Accuracy : ±3%
6. 45μA No Load Quiescent Current
7. Internal Soft Start Limits Startup Current and Output Voltage Overshoot
8. Synchronizable to External 19.8MHz System Clock
9. Over-Temperature and Current Limit Protection
10. Integrated 85mΩ Bypass MOSFET
11. 2MHz Operation

Applications

1. WCDMA or CDMA PA in Cellular Phones, Smartphones, Feature Phones, etc.
2. Express Card
3. PCMCIA Data Cards
