Description

The TLV240x-Q1 (TLV2401-Q1 and TLV2402-Q1) is a family of high voltage (16-V) nano-power operational amplifiers (op amps). The TLV240x-Q1 has an impressively low quiescent current of just 880 nA (typical) and is ideal for battery-powered or "always-on" applications, such as electric vehicle monitoring and protection applications. Reverse battery protection guards the amplifier from an overcurrent 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 low supply current is coupled with extremely low input bias currents enabling them to be used with mega-Ω resistors making them ideal for portable, long active-life applications. DC accuracy is ensured with a low typical offset voltage of 390 µV, CMRR of 120 dB and minimum open loop gain of 130 V/mV at 2.7 V.

The supply voltage extends from 2.5 V to 16 V, with electrical characteristics specified at 2.7 V, 5 V, and 15 V. The 2.5-V operation makes it compatible with Li-Ion battery-powered systems and many micro-power microcontrollers including TI’s MSP430 and MSP432.

The single channel TLV2401-Q1 is available in a 5-pin SOT-23 package, and the dual channel TLV2402-Q1 is available in an 8-pin VSSOP. Both packages are fully specified from –40°C to 125°C.
