TLC271, TLC271A, TLC271B CMOS PROGRAMMABLE LOW POWER OPERATIONAL AMPLIFIERS Description Pin Assignments 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 OFFSET N1 BIAS SELECT available, ranging from the low-cost TLC271 (10mV) to the 1OUT 1 8 Vcc+ TLC271B (2mV) low-offset version. The devices are offered in IN- V 2 1IN- 7 2ODDUT both commercial and industrial operating temperature ranges. IN+ OUT 1IN+ 3 6 2IN- The extremely high input impedance and low bias currents, in GND OFFSET N2 Vcc- 4 5 2IN+ conjunction with good common-mode and supply voltage rejection make these devices an excellent choice for high performance SO-8 designs. The devices also feature low-voltage single-supply operation with a common-mode input voltage range which includes the negative rail. Features Applications Wide range of supply voltages over specified temperature With the programmability options of the TLC271, a designer can range: choose a very low current option allowing for extended battery life or 0C to 70C . 3 V to 16 V choose a higher current option for more performance. It is possible to -40C to 85C . 4 V to 16 V switch performance modes as the application demands change. Single-Supply Operation Common-Mode Input Voltage Range The TLC271 is well suited for many consumer audio, industrial and Extends Below the Negative Rail other low power applications.
