TI's new high-voltage amplifiers enable accuracy in error-sensitive industrial applications

Designers can optimize system performance with industry-leading speed, precision and power consumption

DALLAS, June 19, 2018 — (PRNewswire) —  Texas Instruments (TI) (NASDAQ: TXN) today introduced three new amplifiers with a unique combination of high speed and high precision, allowing designers to create more accurate circuits for error-sensitive applications. The new devices support more precise measurement and faster processing of a wide variety of input signals in test and measurement, medical, and data-acquisition systems. To learn more about TI's new amplifiers, with maximum supply voltages ranging from 27 V to 36 V, see www.ti.com/hvamps-pr.

Designers can select the amplifier architecture that meets their system requirements, with input voltages, bandwidths and key features as follows:

Wider bandwidth and faster speeds
Delivering up to twice the bandwidth and slew rate of competitive devices, TI's new high-voltage amplifiers enable the following system-level benefits:

Optimized precision for error-sensitive applications
The exceptional precisi­on of these high-voltage amplifiers maximizes system accuracy, while reducing the need for external calibration and minimizing bill-of-materials (BOM) cost. Precision benefits include:

Lower power consumption
Consuming up to 80 percent less power than competitive devices, TI's new amplifiers enable low-power operation in high-speed designs:

Tools and support to speed design
Engineers can jump-start the design of their high-voltage systems with the Reference Design Maximizing Signal Dynamic Range for True 10 Vpp Differential Input to 20-Bit ADC.

Package, availability and pricing
TI's new high-voltage amplifiers are available with packages and pricing as listed in the table below. The OPA189 and THS3491 amplifiers are now available in volume quantities through the TI store and authorized distributors. Additionally, the OPA2810DGKEVM evaluation module is available today through the TI store and authorized distributors, with production quantities of the OPA2810 amplifier available in 3Q 2018.
