TI's 36-V rail-to-rail input/output op amp combines low offset and drift with fast settling to improve precision ADC performance
Texas Instruments (TI) introduced the industry's first 36-V rail-to-rail input and output (RRIO) operational amplifier (op amp) to achieve precision offset voltage and drift without using auto-zero techniques. The OPA192 achieves stable offset voltage drift over the full specified temperature range, which eliminates the need for system level calibration.
Fast settling and high-output drive, combined with precision, allows designers to use the device to drive analog-to-digital converters (ADCs) in high-voltage, precision data acquisition systems including test and measurement, and industrial sensors and controls.
Key features and benefits of the OPA192:
Tools and support
The OPA192 is included in four new TI Precision Designs reference design to help engineers quickly evaluate and customize a system:
A TINA-TI™ SPICE model is also available with TI Precision Design circuits to accurately simulate and debug the circuit.
The OPA192 utilizes a DIP adapter evaluation module or a universal op amp evaluation module to quickly evaluate the functionality and versatility of the device.
The OPA192 is also supported by TI's WEBENCH® Filter Designer, an online tool that enables engineers to design, optimize, and simulate complete multi-stage active filter solutions within minutes.
Additional support is available on the Precision Amplifier forum in the TI E2E™ Community, where engineers can search for solutions, get help, share knowledge and solve problems with fellow engineers and TI experts.
Packaging, availability and pricing
The OPA192 is available in the following three package options for a suggested retail price of US$1.35 in 1,000-unit quantities: 5-mm by 4-mm SO-8 package, 3-mm by 3-mm MSOP-8 and 3-mm by 1.75-mm SOT23-5.
