SGLS181C – SEPTEMBER 2003 – REVISED AUGUST 2009 Advanced LinCMOS™ RAIL-TO-RAIL OUTPUT WIDE-INPUT-VOLTAGE OPERATIONAL AMPLIFIERS 23 • Qualified for Automotive Applications • Low Noise: 16 nV/√Hz Typ at f = 1 kHz • ESD Protection Exceeds 2000 V Per • Low Input Offset Voltage: MIL-STD-883, Method 3015; Exceeds 200 V 950 µV Max at T A = 25°C (TLV244xA) Using Machine Model (C = 200 pF, R = 0) • Low Input Bias Current: 1 pA (Typ) • Output Swing Includes Both Supply Rails • 600-Ω Output Drive • Extended Common-Mode Input Voltage Range: • High-Gain Bandwidth: 1.8 MHz (Typ) 0 V to 4.25 V (Min) at 5-V Single Supply • Low Supply Current: 750 µA Per Channel (Typ) • No Phase Inversion • Macromodel Included The TLV244x and TLV244xA are low-voltage operational amplifiers from Texas Instruments. The common-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 common-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 comparable 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 telecommunications applications. The other members in the TLV244x family are the low-power, TLV243x, and micro-power, TLV2422, Figure 1. 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 TLV244xA is available with a maximum input offset voltage of 950 µV. If the design requires single operational amplifiers, see the TI TLV2211/21/31. This is a family of rail-to-rail output operational amplifiers in the SOT-23 package. Their small size and low power consumption make them ideal for high-density battery-powered equipment. 1 Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet. 2 Advanced LinCMOS is a trademark of Texas Instruments. 3 PSpice, Parts are trademarks of MicroSim.
