U\\I75 UUIRA-IINEAR ISOIATION AMPLIIIER WITH E}fiT,RNAt SYNC CAPABITITY Fully Compatible with 12-Bit Acquisition Systems

FEATURES

r Provision for External Synchronization . High Linearity: 0.fi)590 Peak, Typical . High Input/Output Isolation: 5000VDC continuous, 3000vAC Rr\\{s o 10fi):l Programmable Gain . Low Drift: +0.0190/oC Maximum r l26dB Common-Mode Rejection The Model IAl75 Isolation Amplifier features very high linearity, input,/output isolation, and common-mode rejection, very low drift, and externally programmable gain. Its 0.00590 linearity assures compatibility with l2-bit data acquisition systems, and its ability to operate at common-mode input voltages up to 5000 VDC enables operation with single sources in high voltage systems and other hazardous locations. Common-mode rejection is at least 120 dB with source imbalance of up to 5000 ohms. lnput voltage noise is lpV, lOHz to I kHz, and current noise is l0 pA for the same range. The gain of the ampli- fier is programmable from lV,/V to 1000V/V by means of an externally connected resistance value. The internal oscil- lator used to provide modulation and demodulation for input isolation can be synchronized with those of asso- ciated Model IAl75 amplifiers by means of an external trigger, to avoid imposition of beat-frequency phenomena on the output signals. An independent + I4VDC, + l5 mA supply in the input section, with the same voltage isolation as the amplifier input, is used to power an external trans- ducer, or preamplifier.

CMRR is 126 dB input to output with balanced source impedance. CMRR from input to active input reference is 120 dB. This Isolation Amplifier con- tains most of the front-end circuitry that is found in monitor and diagnostic ECG's. The IA294 has a true instrumentation front-end for high CMRR, active right leg drive, sync capability for multichannel use, isolated power ( + l5 V @ l5 mA) and separate active drives for either, individual shielded inputs or a common outer shield.
