ADC claims exceptional AC specifications
Serial-interface 14bit ADC combines high speed, low power and a small package for portable applications such as comms, medical instrumentation and data acquisition.
Available now from Linear Technology, the LTC2356-14 is a 14bit analogue-to-digital convertor (ADC) that communicates via an SPI-compatible serial interface at output rates up to 3.5Msample/s The LTC2356-14 operates from a single 3.3V supply, draws only 18mW at the maximum conversion rate, and is housed in a tiny 10-pin MSOP

Linear launches triple output converter
Linear Technology has revealed the LTC3100, a triple output converter that includes a 700mA (ISW) synchronous boost regulator, a 250mA (IOUT) synchronous buck regulator and a 100mA (IOUT) LDO.
Linear releases dual DC/DC regulator system
Linear Technology has introduced the LTM4616, a dual DC/DC umodule regulator system in a tiny surface mount package.
The LTC2356-14's successive approximation register (SAR) architecture produces a low power ADC with exceptional AC specifications.
The combination of speed, low power and small package makes the LTC2356-14 ideal for high speed, portable applications including communications, medical instrumentation and data acquisition.
The LTC2356-14 achieves 72.3dB SINAD and 82dB SFDR at 1.4MHz.
When measuring +/-1.25V bipolar inputs differentially, the LTC2356-14's -60dB common mode rejection ratio allows users to eliminate common mode noise.
When the ADC is not converting, power dissipation can be reduced to 4mW in "nap" mode, with the internal 2.5V reference remaining active, and 13uW with all internal circuitry powered down in "sleep" mode.
For applications requiring a unipolar input range, the LTC2355-14 is a 14bit SAR ADC that is otherwise identical.
The LTC2355-14 measures 0-2.5V unipolar input voltages.
For lower resolution applications, Linear Technology has released the LTC2356-12 and LTC2355-12, pin- and software-compatible 12bit versions of the LTC2356-14 and LTC2355-14.
The LTC235x-14/-12 ADCs are also pin- and code-compatible with Linear Technology's existing LTC1403 family, allowing users to easily upgrade their designs for faster sample rates.
Pricing begins at US $7.95 each for the LTC2356-14 and LTC2355-14, and at US $4.95 each for the LTC2356-12 and LTC2355-12, in 1000-piece quantities. Request a free brochure from Linear Technology Corp ...
