These devices consist of two independent, high-gain, frequency-compensated operational amplifiers designed to operate from a single supply over a wide range of voltages. Operation from split supplies also is possible if the difference between the two supplies is 3 V to 32 V, and VCC is at least 1.5 V more positive than the input common-mode voltage. The low supply-current drain is independent of the magnitude of the supply voltage.

• Wide supply voltage ranges
• Low supply-current drain independent of supply voltage
• Common-mode input voltage range includes ground, allowing direct sensing near ground
• Low input bias and offset parameters
• Internal frequency compensation

The LTC6090HS8E#PBF is a high voltage precision monolithic Operational Amplifier for use with high voltage regulators. The LTC6090 is unity gain stable. The LTC6090-5 is stable in noise gain configurations of 5 or greater. Amplifier feature high open loop gain, low input referred offset voltage and noise, pA input bias current and ideal for high voltage, high impedance buffering and/or high gain configurations. The amplifier is internally protected against over-temperature conditions. A thermal warning output, TFLAG, goes active when the die temperature approaches 150°C. The output stage may be turned off with the output disable pin OD. By tying the OD pin to the thermal warning output (TFLAG), the part will disable the output stage when it is out of the safe operating area. These pins easily interface to any logic family. Amplifier may be run from a single 140V or spit ±70V power supplies and are capable of driving up to 200pF of load capacitance.

The OPA340NA/3K is a single-supply Operational Amplifier optimized for low-voltage. High-speed operation make them ideal for driving sampling analogue-to-digital (A/D) converters. They are also well-suited for general purpose and audio applications as well as providing I/V conversion at the output of digital-to-analogue (D/A) converters. Single version have identical specifications for design flexibility. The OPA340 series operate on a single supply as low as 2.5V with an input common-mode voltage range that extends 500mV below ground and 500mV above the positive supply. Output voltage swing is to within 1mV of the supply rails with a 100k load.

• Rail-to-rail input/output
• 750µA/channel Low quiescent current
• Green product and no Sb/Br
