TLV2444 Datasheet | Texas Instruments

description The TLV244x and TLV244x A are low-voltage operational amplifiers from Texas Instruments. The mon-mode input voltage range of these devices has been extended over typical standard CMOS amplifiers, making them suitable for a wide range of applications. In addition, these devices do not phase invert when the mon-mode input is driven to the supply rails. This satisfies most design requirements without paying a premium for rail-to-rail input performance. They also exhibit rail-to-rail output performance for increased dynamic range in single- or split-supply applications. This family is fully characterized at 3-V and 5-V supplies and is optimized for low-voltage operation. Both devices offer parable ac performance while having lower noise, input offset voltage, and power dissipation than existing CMOS operational amplifiers. The TLV244x has increased output drive over previous rail-to-rail operational amplifiers and can drive 600-Ω loads for telemunications applications. - High-Level Output Voltage - V HIGH-LEVEL OUTPUT VOLTAGE vs HIGH-LEVEL OUTPUT CURRENT 3 VDD = 3 V 2 TA = - 40°C TA = 125°C TA = 85°C TA = 25°C - High-Level Output Current - m A Figure 1 The other members in the TLV244x family are the low-power, TLV243x, and micro-power, TLV2422, versions. The TLV244x, exhibiting high input impedance and low noise, is excellent for small-signal conditioning for high-impedance sources, such as piezoelectric transducers. Because of the micropower dissipation levels and low-voltage operation, these devices work well in hand-held monitoring and remote-sensing applications. In addition, the rail-to-rail output feature with single- or split-supplies makes this family a great choice when interfacing with analog-to-digital converters (ADCs). For precision applications, the TLV244x A is available with a maximum input offset voltage of 950 µV. If the design requires single operational amplifiers, see the TI...
