Wide Bandwidth 3 MHz High Slew Rate 2.4 V/µs Supply Voltage Range 2.7 V to 16 V Supply Current 550 µA/Channel Low Power Shutdown Mode IDD(SHDN) 25 µA/Channel Input Noise Voltage 39 n V/√Hz Input Bias Current 1 p A Specified Temperature Range −40°C to 125°C Industrial Grade Ultrasmall Packaging − 5 or 6 Pin SOT-23 (TLV2370/1) − 8 or 10 Pin MSOP (TLV2372/3) description The TLV237x single supply operational amplifiers provide rail-to-rail input and output capability. The TLV237x takes the minimum operating supply voltage down to 2.7 V over the extended industrial temperature range while adding the rail-to-rail output swing feature. The TLV237x also provides 3-MHz bandwidth from only 550 µA. The maximum recommended supply voltage is 16 V, which allows the devices to be operated from (±8 V supplies down to ±1.35 V) a variety of rechargeable cells. The CMOS inputs enable use in high-impedance sensor interfaces, with the lower voltage operation making an ideal alternative for the TLC227x in battery-powered applications. The rail-to-rail input stage further increases its versatility. The TLV237x is the seventh member of a rapidly growing number of RRIO products available from TI, and it is the first to allow operation up to 16-V rails with good ac performance. All members are available in PDIP and SOIC with the singles in the small SOT-23 package, duals in the MSOP, and quads in the TSSOP package. The 2.7-V operation makes the TLV237x compatible with Li-Ion powered systems and the operating supply voltage range of many micro-power microcontrollers available today including TI’s MSP430.
