Smallest data converters deliver high integration and performance
DALLAS, Dec. 3, 2018 /PRNewswire/ -- Texas Instruments (TI) (NASDAQ: TXN) today introduced four tiny precision data converters, each the industry's smallest in its class. The new data converters enable designers to add more intelligence and functionality, while shrinking system board space. The DAC80508 and DAC70508 are eight-channel precision digital-to-analog converters (DACs) that provide true 16- and 14-bit resolution, respectively. The ADS122C04 and ADS122U04 are 24-bit precision analog-to-digital converters (ADCs) that feature a two-wire, I2C-compatible interface and a two-wire, UART-compatible interface, respectively.
These new devices join a portfolio of precision ADCs and DACs optimized for a variety of small-size, high-performance or cost-sensitive industrial, communications and personal electronics applications. Examples include optical modules, field transmitters, battery-powered systems, building automation and wearables. For more information, see www.ti.com/smallestDACs-pr and www.ti.com/smallestADCs-pr.
Achieve high performance in compact spaces with the DAC80508 and DAC70508
-- Reduce system size: Both DACs include a 2.5-V, 5-ppm/°C internal
reference, eliminating the need for an external precision reference.
Available in a 2.4-mm-by-2.4-mm die-size ball-grid array (DSBGA) package
or wafer chip-scale package (WCSP), and a 3-mm-by-3-mm quad flat no-lead
(QFN)-16 package, these devices are up to 36 percent smaller than the
competition. The new DACs eliminate the typical trade-off between high
performance and small size, enabling engineers to achieve the best
system accuracy, while reducing board size or increasing channel
density.
-- Maximize system accuracy and achieve higher reliability: In addition to
their compact size, the DAC80508 and DAC70508 provide true, 1 least
significant bit (LSB) integral nonlinearity to achieve the highest level
of accuracy at 16- and 14-bit resolution - up to 66 percent better
linearity than the competition. They are fully specified over a -40°C
to +125°C extended temperature range and provide features such as
cyclic redundancy check (CRC) to increase system reliability.
Reduce system size and achieve high performance with the ADS122C04 and ADS122U04
-- Minimize footprint: These tiny, 24-bit precision ADCs are available in
3-mm-by-3-mm very thin QFN (WQFN)-16 and 5-mm-by-4.4-mm thin-shrink
small-outline package (TSSOP)-16 options. The two-wire interface
requires fewer digital isolation channels than a standard serial
peripheral interface (SPI), reducing the overall cost of an isolated
system. These precision ADCs eliminate the need for external circuitry
by integrating a flexible input multiplexer, a low-noise programmable
gain amplifier, two programmable excitation current sources, an
oscillator and a precision temperature sensor.
-- Improve performance: Both devices feature a low-drift 2.048-V, 5-ppm/°C
internal reference. Their internal 2 percent accurate oscillators help
designers improve power-line cycle noise rejection, enabling higher
accuracy in noisy environments. With gains from 1 to 128 and noise as
low as 100 nV, designers can measure both small-signal sensors and wide
input ranges with one ADC. These device families, which also include
pin-to-pin-compatible 16-bit options, give designers the flexibility to
meet various system requirements by scaling performance up or down.
Tools and support to simplify design
-- Evaluate the new data converters with the DAC80508 evaluation module,
the ADS122C04 evaluation module and the ADS122U04 evaluation module, all
available today for US$99.00 from the TI store and authorized
distributors.
-- Engineers can jump-start their designs using the DAC80508 with the
reference design for laser diode applications with precisely controlled
current requirements and the ADS122C04 and ADS122U04 with the
high-precision temperature measurement for heat and cold meters
reference design.
-- Designers can simulate their designs and predict circuit behavior for
these data converters by downloading the DACx0508 input/output buffer
information specification (IBIS) model, the ADS122C04 IBIS model and the
ADS122U04 IBIS model.
