UNISONIC TECHNOLOGIES CO., LTD ULV1012 Preliminary CMOS IC ANALOG SERIES: PRE-AMPLIFIED IC'S FOR HIGH GAIN 2-WIRE MICROPHONES 6 DESCRIPTION 4 1 The UTC ULV1012 is high gain, high impedance per-amplifier which is designed to replace the JFET amplifier currently being used. The UTC ULV1012 audio amplifiers are specified to operate over a 2.2V to 5.0V supply voltage range with fixed gains of 7.8dB, 15.6dB, 20.9dB, and 23.8dB. The devices offer excellent THD, gain accuracy and temperature stability as compared to a JFET microphone. The UTC ULV1012 series is ideally suited for applications requiring high signal integrity in the presence of ambient or RF noise, such as in cellular communications. The UTC ULV1012 suited for use in headsets, mobile communications, automotive accessories, PDAs, accessory microphone products and telephone Electret Condenser Microphones (ECM). 5 2 3 SOT-26 FEATURES * Typical ULV1012-15, 2.2V Supply, RL=2.2kΩ, C=2.2μF, VIN=18mVPP, Unless Otherwise Specified * Supply Voltage: 2V ~ 5V * Supply Current: <180μA * Voltage Gain – ULV1012-07: 7.8dB – ULV1012-15: 15.6dB – ULV1012-20: 20.9dB – ULV1012-25: 23.8dB * Temperature Range: −40°C~85°C ORDERING INFORMATION Ordering Number ULV1012G-xx-AG6-R www.unisonic.com.tw Copyright © 2016 Unisonic Technologies Co., Ltd Package SOT-26 Packing Tape Reel 1 of 7 QW-R107-073.a ULV1012 CMOS IC MARKING INFORMATION PACKAGE SOT-26 Preliminary VOLTAGE GAIN 07: 15: 20: 25: MARKING 7.8dB 15.6dB 20dB 23.8dB PIN CONFIGURATION 1 6 INPUT GND 2 5 GND OUTPUT 3 4 NC NC Note: Pin numbers are referenced to package marking text orientation.

Absolute maximum ratings are those values beyond which the device could be permanently damaged. Absolute maximum ratings are stress ratings only and functional device operation is not implied. For ensured specifications and the test conditions, see the 5V Electrical Characteristics. 2. Human Body Model (HBM) is 1.5kΩ in series with 100pF. 3. The maximum power dissipation is a function of TJ(MAX), θJA and TA. The maximum allowable power dissipation at any ambient temperature is PD=(TJ(MAX)-TA)/θJA.
