The LTC1402 is a 12-bit, 2.2Msps sampling A/D converter. This high performance device includes a high dynamic range sample-and-hold and a precision reference. It operates from a single 5V supply or dual ±5V supplies and draws only 90mW from 5V.The versatile differential input offers a unipolar range of 4.096V and a bipolar range of ±2.048V for dual supply systems where high performance op amps perform best, eliminating the need for special translation circuitry.The high common mode rejection allows users to eliminate ground loops and common mode noise by measuring signals differentially from the source.Outstanding AC performance includes 72dB S/(N + D) and –93dB SFDR at the Nyquist input frequency of 1.1MHz with dual ±5V supplies and –84dB SFDR with a single 5V supply.The LTC1402 has two power saving modes: Nap and Sleep. Nap mode consumes only 15mW of power and can wake up and convert immediately. In Sleep mode, it typically consumes 10µW of power. Upon power-up from Sleep mode, a reference ready (REFRDY) signal is available in the serial data word to indicate that the reference has settled and the chip is ready to convert.The 3-wire serial port allows compact and efficient data transfer to a wide range of microprocessors, microcontrollers and DSPs. A digital output driver power supply pin allows direct connection to 3V or lower logic.ApplicationsTelecommunicationsHigh Speed Data and Signal AcquisitionDigitally Multiplexed Data Acquisition SystemsDigital Radio ReceiversSpectrum AnalysisLow Power and Battery-Operated SystemsHandheld or Portable InstrumentsImaging Systems

The LTC1403/LTC1403A are 12-bit/14-bit, 2.8Msps serial ADCs with differential inputs. The devices draw only 4.7mA from a single 3V supply and come in a tiny 10-lead MS package. A Sleep shutdown feature lowers power consumption to 10µW. The combination of speed, low power and tiny package makes the LTC1403/LTC1403A suitable for high speed, portable applications.The 80dB common mode rejection allows users to eliminate ground loops and common mode noise by measuring signals differentially from the source.The devices convert 0V to 2.5V unipolar inputs differentially. The absolute voltage swing for +AINand –AINextends from ground to the supply voltage.The serial interface sends out the conversion results during the 16 clock cycles following the rising edge of­ CONV for compatibility 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 2.8Msps can be achieved with a 50.4MHz clock.ApplicationsAutomotiveCommunicationsData Acquisition SystemsUninterrupted Power SuppliesMultiphase Motor ControlMultiplexed Data Acquisition
