Texas Instruments ADC Drivers Set New Standard in Power
Texas Instruments Inc. (TI) expanded its portfolio of general-purpose, low power, rail-to-rail output operational amplifiers (op amps) with the introduction of new single and dual analog-to-digital converter (ADC) drivers that provide the industry’s highest performance-to-power ratio. The OPAx836 op amps use 33 percent less power than similar solutions while providing more than twice the bandwidth, 15 times faster slew rate, 40 times better total harmonic distortion (THD) and 75-percent higher precision.
“Customers designing portable industrial measurement devices, until now, have been limited by op amp performance when designing with 12-, 14- and 16-bit precision SAR and delta-sigma ADCs in their high-precision applications, such as ultrasonic flow meters, smart pumps and power quality meters,” said Steve Anderson, Senior Vice President of TI’s High Performance Analog business. “By providing the industry’s highest performance-to-power ratio, the OPAx836 op amps allow customers to drive these data converters to data sheet performance while providing ultra-low power consumption. These ADC drivers allow designers to extend the battery life of portable industrial and medical devices while delivering high accuracy.”
