TLC2254AIPW

TLC2254AIPW Description

The TLC2254AIPW from Texas Instruments is a general-purpose operational amplifier (op-amp) from the LinCMOS™ series, featuring four independent channels in a 14-TSSOP surface-mount package. Designed for low-power applications, it operates over a wide supply voltage range of 4.4V to 16V, making it versatile for both battery-powered and industrial systems. With an ultra-low input bias current of 1 pA and a moderate gain bandwidth product of 210 kHz, it excels in precision signal conditioning and filtering applications. Despite being obsolete, it remains relevant due to its ROHS3 compliance and REACH unaffected status, ensuring environmental and regulatory compatibility.

TLC2254AIPW Features

• Low Power Consumption: Only 160µA per channel supply current, ideal for portable and energy-efficient designs.
• High Input Impedance: 1 pA input bias current minimizes loading effects in high-impedance sensor interfaces.
• Rail-to-Rail Output: 50 mA output current capability supports robust signal driving.
• Low Offset Voltage: 200 µV input offset enhances DC accuracy in precision circuits.
• Wide Supply Range: 4.4V to 16V operation accommodates diverse power sources.
