Mixed Signal/Analog
14-Bit ADC Dissipates 18mW in 10-Pin MSOP
Linear Technology has introduced the LTC2356-14, a 14-bit analog-to-digital converter that communicates via an SPI-compatible serial interface at output rates up to 3.5Msps. The LTC2356-14 operates from a single 3.3V supply, draws only 18mW at the maximum conversion rate, and is available in a tiny 10-pin MSOP 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 For applications requiring a unipolar input range, Linear Technology is also introducing the LTC2355-14, a 14-bit SAR ADC that is otherwise identical. The LTC2355-14 measures 0V to 2.5V unipolar input voltages. For lower resolution applications, Linear Technology is also introducing the LTC2356-12 and LTC2355-12, pin- and software-compatible 12-bit 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 $7.95 each for the LTC2356-14 and LTC2355-14, and at $4.95 each for the LTC2356-12 and LTC2355-12, in 1,000-piece quantities.
