LTC1992 Family Low Power, Fully Differential Input/Output Amplifier/Driver Family FEATURES DESCRIPTION n Available with Adjustable Gain or Fixed Gain of 1, The LTC 1992 product family consists of five fully differen- 2, 5 or 10 tial, low power amplifiers. The LTC1992 is an unconstrained n 0.3% (Max) Gain Error from 40C to 85C fully differential amplifier. The LTC1992-1, LTC1992-2, n 3.5ppm/C Gain Temperature Coefficient LTC1992-5 and LTC1992-10 are fixed gain blocks (with n 5ppm Gain Long Term Stability gains of 1, 2, 5 and 10 respectively) featuring precision n Fully Differential Input and Output on-chip resistors for accurate and ultrastable gain. All of n C Stable up to 10,000pF the LTC1992 parts have a separate internal common mode LOAD n Adjustable Output Common Mode Voltage feedback path for outstanding output phase balancing n Rail-to-Rail Output Swing and reduced second order harmonics. The V pin sets OCM n Low Supply Current: 1mA (Max) the output common mode level independent of the input n High Output Current: 10mA (Min) common mode level. This feature makes level shifting of n Specified on a Single 2.7V to 5V Supply signals easy. n DC Offset Voltage <2.5mV (Max) The amplifiers differential inputs operate with signals n Available in 8-Lead MSOP Package ranging from rail-to-rail with a common mode level from the negative supply up to 1.3V from the positive supply. APPLICATIONS The differential input DC offset is typically 250V. The rail-to-rail outputs sink and source 10mA. The LTC1992 n Differential Driver/Receiver is stable for all capacitive loads up to 10,000pF. n Differential Amplification n Single-Ended to Differential Conversion The LTC1992 can be used in single supply applications n Level Shifting with supply voltages as low as 2.7V. It can also be used n Trimmed Phase Response for Multichannel Systems with dual supplies up to 5V. The LTC1992 is available in an 8-pin MSOP package.
