Description
The IMP811/IMP812 are low-power supervisors designed to monitor voltage levels of 3.0V, 3.3V and 5.0V power supplies in low-power microprocessor (μP), microcontroller (μC) and digital systems. Each features a debounced manual reset input. The IMP811/812 are improved drop-in replacements for the Maxim MAX811/812 with extended temperature specifications to 105°C.
A reset signal is issued if the power supply voltage drops below a preset threshold and is asserted for at least 140ms after the supply has risen above the reset threshold. The IMP811 has an active-low output RESET that is guaranteed to be in the correct state for VCC down to 1.1V. The IMP812 has an active-high output RESET. The reset comparator is designed to ignore fast transients on VCC .
Low power consumption makes the IMP811/IMP812 ideal for use in portable and battery-operated equipment. Available in a compact 4-pin SOT143 package, the devices use minimal board space.

DESCRIPTION
The AIC1660 is a monolithic CMOS switched capacitor voltage converter. Designed to be an improved direct replacement for the popular 7660 and LTC1044, the main function of the AIC1660 is to convert a positive input voltage in the range of 1.5V to 6V to the corresponding negative output voltage in the range of -1.5V to -6V. The input voltage can also be doubled (VOUT = 2VIN ), divided (VOUT = VIN /2 ), or multiplied (VOUT = ±nVIN), as shown in application examples.
The chip contains a series DC power supply regulator, oscillator, control circuitry and four output power MOS switches. The frequency of oscillator can be lowered by the addition of an external capacitor to the OSC pin, or the oscillator may be over-driven by an external clock.
The boost function is available to raise the oscillator frequency to optimize performance in specific applications. The “LV” terminal may be tied to GND to improve low input voltage (VIN £3V) operation, or be left floating for input voltage larger than 3V to improve power dissipation.
The AIC1660 provides performance superior to previous designs by combining low output impedance, low quiescent current with high efficiency, and by eliminating diode drop voltage losses. The only required external components are two low cost electrolytic capacitors.

FEATURES
*Lowest Output Impedance (Typical 35W at VIN=5V).
*Improved Direct Replacement for 7660.
*1.5V to 6V Operation.
*No External Diode Required.
*Simple Conversion of +5V to -5V.
*Low Quiescent Current (Typical 36mA at VIN=5V).
*High Power Efficiency (Typical 98%)
*Boost Pin for Higher Switching Frequency.
*Improved SCR Latchup Protection.

APPLICATIONS
*RS-232 Power Supplies.
*Handheld Instruments.
*Data Acquisition Systems.
*Supply Splitter, VOUT= ±VIN /2.
*Operational Amplifier Supplies.
*Panel Meter.

DESCRIPTION
TK10651 is a noise reduction IC developed mainly for cordless phones. It is also used for voice and data communications. It has a built-in compressor circuit to increase the average modulation level and an expander circuit to reduce the noise level. The expander restores the
original dynamics of the input signal. The result is a high quality signal transmission with low noise. Among the many functions included, analog switching of the input and output signal is particularly useful in cordless telephones. Separate data input and output are provided. The audio signal path can be muted during data transmission. The signal path used for data transmission bypasses the compressor and expander circuits.

FEATURES
*Data and Voice Inputs
*Data and Voice Outputs
*Low Supply Current
*Regulated Output
*Wide Operating Voltage Range
*Low Standby Current
*Microphone Amplifier
*IDC Circuit (Instantaneous Deviation Control)
