TI launches low distortion op amps

Texas Instruments has announced a new series of high-speed operational amplifiers that combine low distortion with low noise.

Texas Instruments has announced a new series of high-speed operational amplifiers (op amps) that combine ultra low distortion with ultra low noise.

Based on a voltage-feedback design, the THS4271/5 op amps offer unity gain stability with 1.4 GHz unity-gain bandwidth, along with 900V/us slew rate and a 2.8 nanovolts per root-hertz voltage noise density. With a 2-volt peak-to-peak output signal, the THS4271/5 offers the industry’s lowest distortion of -84 decibels below the carrier (dBc) at 30 MHz.

To enhance performance characteristics, the THS4271/5 will be the first high speed op amps from TI to be available in a leadless miniature small outline package (MSOP).

In wireless base stations, THS4271/5 family of op amps can drive high-speed 14-bit data converters, helping eliminate intermediate signal stages to reduce system costs. They can also be used in phase look loop (PLL) filter circuits. Filtering, gain stages and signal conditioning in automatic test equipment (ATE) and measurement instrumentation can benefit from the speed, low noise and low distortion of the devices. In mixed-signal tester equipment, for instance, the op amps will enable ATEs to match the operating speed of the next-generation integrated circuits that are being tested.

The THS4271/5 op amps are sampling now, with volume production scheduled to start in September. All THS4271/5 devices will be available in a leadless MSOP and MSOP.

Planned pricing per unit in quantities of 1,000 units is $2.69.
