TLC271IS-13

TLC271, TLC271A, TLC271B CMOS PROGRAMMABLE LOW POWER OPERATIONAL AMPLIFIERS Description Pin Assignments New Product The TLC271 operational amplifier combines a wide range of input offset voltage grades with low offset voltage drift and high input impedance. In addition, the TLC271 offers a bias-select mode that allows the user to select the best combination of power dissipation and AC performance for a particular application. (Top View) Using the bias-select option, these devices can be programmed to fit a wide range of applications. Three offset voltage grades are available, ranging from the low-cost TLC271 (10mV) to the TLC271B (2mV) low-offset version. The devices are offered in both commercial and industrial operating temperature ranges. OFFSET N1 1OUT IN1IN- The extremely high input impedance and low bias currents, in conjunction with good common-mode and supply voltage rejection make these devices an excellent choice for high performance designs. 1 8 2 IN+ 1IN+ 3 GND Vcc- 4 7 BIAS Vcc+ SELECT V 2OUT DD 6 5 OUT 2INOFFSET N2 2IN+ SO-8 The devices also feature low-voltage single-supply operation with a common-mode input voltage range which includes the negative rail. Features Applications  With the programmability options of the TLC271, a designer can choose a very low current option allowing for extended battery life or choose a higher current option for more performance. It is possible to switch performance modes as the application demands change.           Wide range of supply voltages over specified temperature range: 0°C to 70°C . . . 3 V to 16 V -40°C to 85°C . . . 4 V to 16 V Single-Supply Operation Common-Mode Input Voltage Range Extends Below the Negative Rail Low Noise: 20 nV/√Hz Typical @ f = 1kHz (High-Bias Mode) Output Voltage Range Includes Negative Rail High Input Impedance ESD-Protection Circuitry Designed-In Latch-Up Immunity Totally Lead-Free & Fully RoHS Compliant (Notes 1 & 2) Halogen and Antimony Free. “Green” Device (Note 3) The TLC271 is well suited for many consumer audio, industrial and other low power applications.    Notes: Audio Microphone Preamplifier Filtering – Equalizers Signal Amplification Industrial Power Supply Instrumentation Metering Medical Portable Meters and Measurement Instrumentation 1.
