Texas Instruments THS3091 THS3095 High-Voltage, Low-Distortion, Current-Feedback Operational Amplifiers
Summary
The THS3091/THS3095 are high-performance, low-distortion current-feedback operational amplifiers engineered for demanding, high-voltage applications. Designed with a wide supply range ($\pm 5$ V to $\pm 15$ V), they feature exceptional specifications including a high slew rate and superior bandwidth. The THS3095 adds power-down functionality for low-power modes. This technical manual provides detailed operating conditions, package information, performance graphs (THD vs. Frequency), and dissipation ratings necessary for designers creating Pin, Power FET, or VDSL line driver circuits that require accurate arbitrary waveform generation.

Frequently Asked Questions
Which model supports a power-down standby mode?
The THS3095 features a Power-Down pin (PD) to lower quiescent current.
How should I handle the device during storage or handling?
To prevent ESD damage, the leads must be shorted together or the device placed in conductive foam.
What is required for proper power dissipation on the DDA package?
The PowerPAD™ acts as a heatsink and must be connected to a thermally dissipating plane.
What voltage range can the THS3091/5 operate over?
These devices are ideal for high-voltage applications, operating between ±5 V to ±15 V.
