TLC227x, TLC227xA: Advanced LinCMOS Rail-to-Rail Operational Amplifiers 1 Features
The TLC227x also make great upgrades to the TLC27x in standard designs. They offer increased • Output Swing Includes Both Supply Rails 1 output dynamic range, lower noise voltage, and lower • Low Noise: 9 nV/√Hz Typical at f = 1 kHz input offset voltage. This enhanced feature set allows • Low-Input Bias Current: 1-pA Typical them to be used in a wider range of applications. For applications that require higher output drive and wider • Fully-Specified for Both Single-Supply and Split- input voltage range, see the TLV2432 and TLV2442 Supply Operation devices. • Common-Mode Input Voltage Range Includes Negative Rail If the design requires single amplifiers, see the TLV2211, TLV2221 and TLV2231 family. These • High-Gain Bandwidth: 2.2-MHz Typical devices are single rail-to-rail operational amplifiers in • High Slew Rate: 3.6-V/μs Typical the SOT-23 package. Their small size and low power • Low Input Offset Voltage: 950 μV Maximum at consumption make them ideal for high density, T battery-powered equipment. A = 25°C • Macromodel Included
