ADC drivers claims new standard in power and performance to increase accuracy and battery life
“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.”
For customers needing even lower power for battery-operated consumer electronics, such as cameras, notebooks and cell phones, the OPAx835 ADC drivers are also available. The OPAx835 op amps use 60-percent less power than the competition while still providing a best-in-class performance-to-power ratio.
Evaluation modules (EVMs) are available today for the single-channel OPA836
(OPA836IDBVEVM) and dual OPA2836 (OPA2836IDGSEVM) for a suggested retail price of $99 and $149, respectively. A reference design for the OPA836 is also available with the ADS7945 (ADS7945EVM-PDK) and ADS7946
(ADS7946EVM-PDK).
EVMs for the single-channel OPA835 (OPA835IDBVEVM) and dual OPA2835
(OPA2835IDGSEVM) can be purchased today for a suggested retail price of $99 and $149, respectively.
PSpice and TINA-TI Spice models and TINA-TI reference designs are also available for all four devices.
Availability and Pricing
Samples and production quantities of the single-channel OPA836 and OPA835 are available in two package options: 1) a 10-pin, 2-mm x 2-mm WQFN, or 2) a 6-pin, 3-mm x 3-mm SOT23. Suggested retail pricing for 1,000 units is $0.90 for the OPA836 and $ 0.85 for the OPA835.
Samples and production quantities of the dual OPA2836 and OPA2835 are available today in three package options: 1) an 8-pin, 4-mm x 5-mm SOIC, 2) a 10-pin, 3-mm x 3-mm MSOP, or 3) a 10-pin, 2-mm x 2-mm WQFN. Suggested retail pricing for 1,000 units is $1.50 for the OPA2836 and $1.35 for the OPA2835.
