The LT1993-2 is a low distortion, low noise Differential Ampli?er/ADC driver for use in applications from DC to 800MHz. The LT1993-2 has been designed for ease of use, with minimal support circuitry required. Exceptionally low input-referred noise and low distortion products (with either single-ended or differential inputs) make the LT1993-2 an excellent solution for driving high speed 12-bit and 14-bit ADCs. In addition to the normal un? ltered outputs (+OUT and ?OUT), the LT1993-2 has a built-in 175MHz differential low pass ?lter and an additional pair of ?ltered outputs (+OUTFILTERED, ?OUTFILTERED) to reduce external ?ltering components when driving high speed ADCs. The output common mode voltage is easily set via the VOCM pin, eliminating either an output transformer or AC-coupling capacitors in many applications.The LT1993-2 is designed to meet the demanding requirements of communications transceiver applications. It can be used as a differential ADC driver, a general-purpose differential gain block, or in any other application requiring differential drive. The LT1993-2 can be used in data acquisition systems required to function at frequencies down to DC.The LT1993-2 operates on a 5V supply and consumes 100mA. It comes in a compact 16-lead 3 ? 3 QFN package and operates over a ?40?C to 85?C temperature range.Applications Differential ADC Driver for: Imaging Communications Differential Driver/Receiver Single Ended to Differential Conversion Differential to Single Ended Conversion Level Shifting IF Sampling Receivers SAW Filter Interfacing/Buffering

The ADA4530-1 is a femtoampere (10?15 A) level input bias current operational amplifier suitable for use as an electrometer that also includes an integrated guard buffer. It has an operating voltage range of 4.5 V to 16 V, enabling it to operate in conventional 5 V and 10 V single supply systems as well as ?2.5 V and ?5 V dual supply systems.It provides ultralow input bias currents that are production tested at 25?C and at 125?C to ensure the device meets its performance goals in user systems. The integrated guard buffer isolates the input pins from leakage in the printed circuit board (PCB), minimizes board component count, and enables easy system design. The ADA4530-1 is available in an industry-standard surface-mount 8-lead SOIC package with a unique pinout optimized to prevent signals from coupling between the sensitive input pins, the power supplies, and the output pin while enabling easy routing of the guard ring traces.The ADA4530-1 also offers low offset voltage, low offset drift, and low voltage and current noise needed for the types of applications that require such low leakages.To maximize the dynamic range of the system, the ADA4530-1 has a rail-to-rail output stage that can typically drive to within 30 mV of the supply rails under a 10 k? load.The ADA4530-1 operates over the ?40?C to +125?C industrial temperature range and is available in an 8-lead SOIC package.Applications Laboratory and analytical instrumentation: spectrophotometers, chromatographs, mass spectrometers, and potentiostatic and amperostatic coulometry Instrumentation: picoammeters and coulombmeters Transimpedance amplifier (TIA) for photodiodes, ion chambers, and working electrode measurements High impedance buffering for chemical sensors and capacitive sensors

The ADA4851-1 (single), ADA4851-2 (dual), and ADA4851-4 (quad) are low cost, high speed, voltage feedback rail-to-rail output op amps. Despite their low price, these parts provide excellent overall performance and versatility. The 130 MHz, ?3 dB bandwidth and high slew rate make these amplifiers well suited for many general-purpose, high speed applications.The ADA4851 family is designed to operate at supply voltages as low as +3 V and up to ?5 V. These parts provide true single-supply capability, allowing input signals to extend 200 mV below the negative rail and to within 2.2 V of the positive rail. On the output, the amplifiers can swing within 60 mV of either supply rail.With their combination of low price, excellent differential gain (0.08%), differential phase (0.09?), and 0.1 dB flatness out to 11 MHz, these amplifiers are ideal for consumer video applications.The ADA4851 family is designed to work over the extended temperature range (?40?C to +125?C). The ADA4851-4W and ADA4851-2W are automotive grade versions, qualified for ?40?C to +125?C operation per AEC-Q100.

The ADA4858-3 (triple) is a single-supply, high speed current feedback amplifier with an integrated charge pump that eliminates the need for negative supplies to output negative voltages or output a 0 V level for video applications. The 600 MHz, ?3 dB bandwidth and 600 V/?s slew rate make this amplifier well suited for many high speed applications. In addition, its 0.1 dB flatness out to 85 MHz at G = 2, along with its differential gain and phase errors of 0.01% and 0.02? into a 150 ? load, make it well suited for professional and consumer video applications.This triple operational amplifier is designed to operate on supply voltages of 3.3 V to 5 V, using only 42 mA of total quiescent current, including the charge pump. To further reduce the power consumption, it is equipped with a power-down feature that lowers the total supply current to as low as 2.5 mA when the amplifier is not being used. Even in power-down mode, the charge pump can be used to power external components. The maximum output current for external use is 50 mA at ?3 V. The amplifier also has a wide input common-mode voltage range that extends from 1.8 V below ground to 1.2 V below the positive rail at a 5 V supply.The ADA4858-3 is available in a 16-lead LFCSP, and it is designed to work over the extended industrial temperature range of ?40?C to +105?C.ApplicationsProfessional videoConsumer videoImagingActive filtersData Sheet, Rev.
