New Low-Noise, High-Speed Op Amp From Texas Instruments Drives 16-Bit Systems

Texas Instruments

First Device Manufactured Using TI's New Advanced Analog Process

June 3, 2003- Texas Instruments (TI) Incorporated announced a low-noise, high-speed CMOS operational amplifier (op amp) from the company's Burr-Brown product line. This voltage-feedback op amp, which is designed for 16-bit resolution systems, is the first product to be manufactured using TI's new HPA07 precision analog process. (See'

High bandwidth (180MHz), low noise (3nV/rtHz), fast settling (150ns to 0.0015%) and low harmonic distortion (0.003%) make the OPA300 ideal for driving the industry's highest performance 16-bit analog-to-digital converters (ADCs), such as TI's ADS8401 and ADS8402 - the industry's first 16-bit SAR data converters to surpass 1MSPS (1.25MSPS).

Single-supply applications will benefit from operation on 2.7V (+/-1.35V) and 5.5V (+/-2.75V). Power-sensitive applications will benefit from a shutdown function that reduces quiescent current (7mA) to 2uA. The OPA300 features rail-to-rail output swing (100mV typically) and wide common-mode range. In addition to buffering 16- and 18-bit ADCs, the OPA300 is well suited to low-noise preamplifier, IF/RF amplifier and active filtering applications. It is specified over the extended industrial temperature range of -40C to +125C.

High-Performance Analog Manufacturing Process

TI's HPA07 process offers the industry's lowest CMOS noise performance, very precise thin-film resistors, higher levels of integration and high-volume 200mm wafer production. TI currently has over 30 products in development on HPA07 that will take advantage of its increased analog performance. (For more information on HPA07, see'

Available Today

The OPA300 comes in SO-8 packages, and is available now from TI and its authorized distributors. SOT23-6 packaging will be available in Q3 2003. Suggested resale pricing starts at $1.25 in 1,000 piece quantities.
