Following up on Deepali’s
post last month, we’ve officially announced new general-purpose, low-power,
rail-to-rail output op amps for driving low-power SAR and delta-sigma ADCs that provide the industry’s
highest performance-to-power ratio.
The single OPA836 and dual OPA2836 use 33% less power than
similar solutions while providing more than twice the bandwidth, 15 times
faster slew rate, 40 times better THD and 75% higher precision.
For customers needing even
lower power for battery-operated consumer electronics, we now have the single OPA835 and dual OPA2835 ADC drivers. These op amps
use 60% less power than the competition while still providing a best-in-class
Paul McGoldrick of
En-Genius.net analyzed the devices and posted his thoughts earlier this week,
“The single OPA836 and the dual OPA2836 . . . stand out from the crowd
with typical 1 mA quiescent current per channel while offering 200 MHz
unity-gain bandwidth . . . The OPA836 and the OPA2836 are going to find
multiple applications in driving ADCs (low-power SAR and delta-sigma) up to 12
bits and in many other low-power signal circuits, especially wideband video.
The incorporation of the gain resistors in the RUN version of the single
channel op amp will save some dramatic amounts of real estate. Both products
are priced well and will be extremely successful.”

Texas Instruments ADC drivers set new standard in power and performance to increase accuracy and battery life
Driver amplifiers provide best-in-class power
consumption, bandwidth, slew rate, total harmonic distortion and precision
DALLAS (Nov. 7, 2011) – Texas
Instruments Incorporated (TI) (NYSE: TXN) today 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. For
more information and to order samples, visit www.ti.com/opa2836-pr.
“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. For more information on the OPAx835 op amps, visit www.ti.com/opa2835-pr.
Key features and
benefits of the OPAx836 ADC drivers:
Tools and support
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.
packaging 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
Yes , It is a very good amplifier .We will start using for driving 16 bits SAR ADC. where we have up to 30 ADC on board .
The only drawback is the reduced settling time (compared to what we actually used i.e the OPA890). This is not an issu but can be in futher
