High-speed Op Amp Establishes New Performance Levels
New Process Enables Faster, Lower-cost Devices
DALLAS (Dec. 29, 1997) -- Continuing to leverage its analog technological expertise, Texas Instruments introduces a new 30-volt high speed operational amplifier (op amp). The wide operating voltage makes this device suitable for a variety of applications. Additionally, with a fast 300-MHz bandwidth, 400-V per microsecond slew rate and 30 nanosecond settling time, this device is well-suited for video applications such as graphic scanners, set top boxes for cable television, medical imaging devices and signal processing systems like radar and sonar equipment.
"It is very important in today’s demanding high-speed applications like digital TV that op amps be capable of high performance," said Eric Droge, TI's marketing specialist for high-speed op amps. "High performance means more than just high bandwidth. Slew rate, settling time and bandwidth are all equally important in any design. Additionally, TI's HVBiCom process, which is used for this device, is highly efficient. As a result, the price-performance of this new high speed op amp is the best in the industry."
Fast Slew Rates, Low Settling Time
The 30V device, which is designated the THS4001, can be used with a wide range of supply voltages and is fully characterized at +/-15 V, +/-5 V and 5 V single supply. The THS4001 minimizes harmonic distortion, while the settling time of less than 30 nanoseconds minimizes bounce in the output signal. Both are critical for signal integrity in high-speed applications.
HVBiCom Process
The THS4001 is fabricated using TI’s high-voltage complementary bipolar (HVBiCom) process, which produces devices that have full dielectric isolation rather than the simple junction isolation of other bipolar processes. The results of the HVBiCom process are devices with higher bandwidth performance, faster slew rates and smaller die sizes. These characteristics allow HVBiCom devices to achieve much improved price-performance levels when compared with older BiCom processes.
Pricing and Availability
The THS4001 comes in an eight-pin SOIC (small outline integrated circuit) package. The THS4001 is available now from Texas Instruments and its authorized distributors. Suggested resale pricing in quantities of 1,000 is $1.29.
