TLV2262CDR

The TLV2262CDR from Texas Instruments is a dual low-voltage operational amplifier designed for single or split supply applications. It offers rail-to-rail output performance, increasing dynamic range. This device provides a compromise between micropower consumption and AC performance, making it suitable for battery-powered applications while maintaining adequate AC characteristics.

Key electrical specifications include a wide supply voltage range of 2.7 V to 8 V and a low supply current of 500 µA maximum per amplifier. It exhibits low noise performance with a typical noise voltage of 12 nV/√Hz at 1 kHz and low input bias current of 1 pA typical. The TLV2262CDR is fully specified for both single-supply and split-supply operation, with a common-mode input voltage range that includes the negative rail.

This operational amplifier family is optimized for low-voltage applications and offers improved noise performance over previous CMOS amplifier generations. The TLV226x family is characterized at 3 V and 5 V. The TLV226xA variants are available with a maximum input offset voltage of 950 µV at 25°C.

The TLV2262CDR is ideal for small-signal conditioning for high-impedance sources, such as piezoelectric transducers, due to its high input impedance and low noise. Its low power dissipation and 3-V operation make it suitable for hand-held monitoring and remote-sensing applications. The rail-to-rail output feature is beneficial when interfacing with analog-to-digital converters (ADCs).
