TheLTC2066/LTC2067/LTC2068are single, dual, and quad low power, zero-drift, 100kHz amplifiers. The LTC2066/LTC2067/LTC2068 enable high resolution measurement at extremely low power levels.Typical supply current is 7.5μA per amplifier with a maximum of 10μA. The available shutdown mode has been optimized to minimize power consumption in duty-cycled applications and features low charge loss during powerup, reducing total system power.The LTC2066/LTC2067/LTC2068’s self-calibrating circuitry results in very low input offset (5μV max) and offset drift (0.02μV/°C). The maximum input bias current is only 35pA and does not exceed 150pA over the full specified temperature range. The extremely low input bias current of the LTC2066/LTC2067/LTC2068 allows the use of high value power-saving resistors in the feedback network.With its ultralow quiescent current and outstanding precision, the LTC2066/LTC2067/LTC2068 can serve as a signal chain building block in portable, energy harvesting and wireless sensor applications.The LTC2066 is available in 6-lead SC70 and 5-lead TSOT-23 packages. The LTC2067 is available in 8-lead MSOP and 10-lead DFN packages. The LTC2068 is available in 14-lead TSSOP and 16-lead 3mm × 3mm QFN packages. These devices are fully specified over the –40°C to 85°C and –40°C to 125°C temperature ranges.ApplicationsSignal Conditioning in Wireless Mesh NetworksPortable Instrumentation SystemsLow-Power Sensor ConditioningGas DetectionTemperature MeasurementMedical InstrumentationEnergy Harvesting ApplicationsLow Power Current Sensing

The LTC2122 is a 2-channel simultaneous sampling 170Msps 14-bit A/D converter with serial JESD204B outputs. It is designed for digitizing high frequency, wide dynamic range signals. It is perfect for demanding communications applications with AC performance that includes 70dBFS SNR and 90dBFS spurious free dynamic range (SFDR). The 1.25GHz input bandwidth allows the ADC to under-sample high frequencies.The JESD204B serial interface simplifies the PCB design by minimizing the number of data lines required. At 170Msps, only two 3.4Gbps output lanes are required. For sample rates up to 150Msps, both ADCs may share the same output lane at up to 6.0Gbps.The DEVCLK+and DEVCLK–inputs can be driven differentially with sine wave, PECL, or LVDS signals. An optional clock divide-by-two circuit or clock duty cycle stabilizer maintains high performance at full speed for a wide range of clock duty cycles.ApplicationsCommunicationsCellular Base StationsSoftware Defined RadiosMedical ImagingHigh Definition VideoTest and Measurement Instrumentation
