Lead temperature 1,6 mm (1/16 inch) from case for 10 seconds. . . . . . . . 260 DescriptionThe TLV270x combines sub-micropower operational amplifier and comparator into a single package that produces excellent micropower signal conditioning with only 1.4A of supply current. This combination gives the designer more board space and reduces part counts in systems that require an operational amplifier and comparator. The low supply current makes it an ideal choice for battery powered portable applications where quiescent current is the primary concern. Reverse battery protection guards the amplifier from an over-current condition due to improper battery installation. For harsh environments, the inputs can be taken 5 V above the positive supply rail without damage to the device.
The TLV270x's low supply current is coupled wit extremely low input bias currents enabling them to be used with mega-ohm resistors making them ideal for portable, long active life, applications. DC accuracy is ensured with a low typical offset voltage as low as 390V, CMRR of 90 dB, and minimum open loop gain of 130 V/mV at 2.7 V.
The maximum recommended supply voltage of TLV270x is as high as 16 V and ensured operation down to 2.5 V, with electrical characteristics specified at 2.7 V, 5 V, and 15V.The 2.5-V operation makes it compatible with Li-Ion battery-powered systems and many micro-power microcontrollers available today including TI's MSP430
All members of TLV270x are available in PDIP and SOIC with the duals, one op-amp and one comparator, in the small MSOP package and quads, two operational amplifiers and two comparators, in the TSSOP package.
