Milpitas, Calif. Linear Technology introduced the LTC2356-14, a 14-bit analog-to-digital converter (ADC) that communicates via an SPI-compatible serial interface at output rates up to 3.5 Msps. The LTC2356-14 operates from a single +3.3-V supply, draws 18-mW power at the maximum conversion rate, and is available in a 10-pin MSOP package. Markets include high speed, portable applications including communications, medical instrumentation, and data acquisition.
The LTC2356-14 achieves 72.3-dB SINAD and 82-dB SFDR at 1.4MHz. While measuring +/-1.25-V bipolar inputs differentially, the LTC2356-14's -60dB common mode rejection ratio allows users to eliminate noise. When the ADC is not converting, power dissipation can be reduced to 4-mW in nap mode, with the internal 2.5-V reference remaining active; and 13-μW with all internal circuitry powered down in sleep mode.
