Low-Power ADCs with Simple Serial
Interfaces in Tiny Packages |
| |
 Arrow Electronics and Linear Technology
present a family of low-power ADCs with simple serial interfaces in tiny packages.
As board space and system power budgets become more constrained, data converter designers are switching to smaller packages, lower power voltages, and SAR ADCs that dissipate only a few milliwatts of power. These ADCs with simple serial interfaces are available in tiny MSOP and QFN packages. Whether you are digitizing a single analog signal or multiple signals simultaneously, Arrow and Linear Technology have the right low-power SAR ADC for you.

| Linear Technology features an extensive family of fast, low-power 14-bit and 12-bit SAR ADCs. These ADCs are available in a 10-pin MSOP package and measure differential analog inputs with dedicated unipolar and bipolar input range versions. The LTC2355-14/LTC2355-12 and LTC2356-14/LTC2356-12 are all capable of converting up to 3.5Msps. The LTC1403 ADCs convert up to 2.8Msps and dissipate 3mW less power. Both of these single-channel ADC families are pin- and software-compatible. The LTC1407 ADCs simultaneously sample two differential analog inputs at output rates up to 3Msps for one channel and 1.5Msps for both channels. |
