The TLV2432 and TLV2442 are a family of wide input voltage, high output drive CMOS operational amplifiers.

Both devices exhibit rail-to-rail output performance with single or split supplies making them an ideal choice when interfacing directly to Analog-to-Digital Converters (ADCs). The TLV2442 and TLV2432 gives the designer two speed vs. power options. The TLV2432 only requires 98 µA per channel (typ) of supply current and is excellent for battery powered, low voltage applications. Along with micropower operation, the TLV2432
has only 22 (@ 1 kHz) of input noise voltage. The TLV2442 offers 1.75 MHz of gain-bandwidth and 1.3 V/µs slew rate for applications demanding higher speed. This AC performance is obtained at only a cost of 750 µA per channel (typ) of supply current. Tighter input offset voltage grades are available for both devices and offer the user a maximum input offset voltage of only 950 µV. This low input offset voltage coupled with a noise voltage of 18 (TLV2442), offers the designer an amplifier for precision applications. The common-mode input range has been extended over previous CMOS amplifiers making these devices available for a wider range of applications. This wide input dynamic range makes these amplifiers good choices for interfacing with Digital-to-Analog Converters (DACs). The TLV2432 and TLV2442 can also drive 600 loads for telecom applications.

This family of products is ideal for your next generation applications. The expanded feature set allows engineers more flexibility with their designs. These products are ideal upgrades to the TI TLC27x family of op amps. The TLV24x2 family is characterized at 3 and 5 V and available in 8-pin SOIC and TSSOP packages.
