New Family of Wide Input Range Rail-to-Rail Output Operational Amplifiers Expands Texas Instruments Line of Single-Supply Op Amp Solutions

DALLAS (Jan. 27, 1997) - Further enhancing its line of single-supply operational amplifier solutions, Texas Instruments (TI) announces a new family of wide input range, rail-to-rail output operational amplifiers. The rail-to-rail output performance makes these devices perfect for interfacing with analog-to-digital (ADC) converters, and are ideal in applications such as cellular phones, notebook computers, modems and PCMCIA cards.

These new devices, designated the TLV2432 and the TLV2442 display up to three times less noise voltage than current market amplifiers. This family offers designers two speeds versus power options. The TLV2432 has low supply current for minimal battery consumption. The TLV2442 offers better AC performance for higher-speed applications. The input common mode range has been extended over typical standard CMOS amplifiers, making the TLV2432 and the TLV2442 available for a broader variety of applications. Their high input impedance and low noise make these devices appropriate for small-signal conditioning for high-impedance sources such as piezoelectric sensors. The TLV2432 and the TLV2442 can also drive 600 loads for telecom applications.
