TI Introduces High-Voltage Version of Industry-Leading Current-Feedback Amplifier
DALLAS (June 8, 2005) – Texas Instruments (TI) (NYSE: TXN) announced today that it has extended the operating voltage of its popular high-speed, current-feedback amplifier with a new high voltage version. The new version matches the original device’s fast slew rate and settling time, high bandwidth and low input referred voltage noise while extending the operating voltage to 37V. The THS3001HV is ideal for large-signal applications requiring excellent transient response, low noise and low distortion, such as in test and measurement, communications and imaging. (See www.ti.com/sc05130.)
The THS3001HV extends the performance of the THS3001, the industry’s fastest 33V high-speed, current feedback amplifier, to 37V (+/-18.5V) power supply systems to allow for increased output voltage swings up to 33V peak-to-peak and increased common-mode operating range. The THS3001 outperforms competing devices in bandwidth, slew rate and distortion performance. The THS3001HV features the same fast slew rate of 6500V/µs, 40 ns settling time, 420 MHz bandwidth and 1.6 nV/rtHz input referred voltage noise plus the extended voltage range.
The THS3001HV is available now in volume from TI and its authorized distributors in an eight-pin mini small-outline package (MSOP) with PowerPad®. The device will also be available mid-summer 2005 in an eight-pin small-outline integrated circuit (SOIC) package. Suggested resale pricing in quantities of 1,000 is $5.00 for the commercial temperature grade (0C to 70C) and $5.15 for the industrial temperature grade (-40C to 85C). Samples are available for 24-hour delivery.
