LTC2355-12/LTC2355-14 Serial 12-Bit/14-Bit, 3.5Msps Sampling ADCs with Shutdown Features 3.5Msps Conversion Rate - 74.2d B SINAD at 14-Bits, 71.1d B SINAD at 12-Bits - Low Power Dissipation: 18m W - 3.3V Single Supply Operation .. - 2.5V Internal Bandgap Reference can be Overdriven - 3-Wire SPI-patible Serial Interface - Sleep (13µW) Shutdown Mode - Nap (4m W) Shutdown Mode - 80d B mon Mode Rejection - 0V to 2.5V Unipolar Input Range - Tiny 10-Lead MSOP Package - DESCRIPTIO The LTC®2355-12/LTC2355-14 are 12-bit/14-bit, 3.5Msps serial ADCs with differential inputs. The devices draw only 5.5m A from a single 3.3V supply and e in a tiny 10-lead MSOP package. A Sleep shutdown feature further reduces power consumption to 13µW. The bination of speed, low power and tiny package makes the LTC2355-12/ LTC2355-14 suitable for high speed, portable applications. The 80d B mon mode rejection allows users to eliminate ground loops and mon mode noise by measuring signals differentially from the source. The devices convert 0V to 2.5V unipolar inputs differentially. The absolute voltage swing for AIN+ and AIN- extends from ground to the supply voltage. The serial interface sends out the conversion results during the 16 clock cycles following a CONV rising edge for patibility with standard serial interfaces. If two additional clock cycles for acquisition time are allowed after the data stream in between conversions, the full sampling rate of 3.5Msps can be achieved with a 63MHz clock. , LT, LTC and LTM are registered trademarks of Linear Technology Corporation.
