LM363D
LM363 Precision Instrumentation Amplifier General Description The LM363 is a monolithic true instrumentation amplifier It requires no external parts for fixed gains of 10 100 and 1000 High precision is attained by on-chip trimming of offset voltage and gain A super-beta bipolar input stage gives very low input bias current and voltage noise extremely low offset voltage drift and high common-mode rejection ratio A two-stage amplifier design yields an open loop gain of 10 000 000 and a gain bandwidth product of 30 MHz yet remains stable for all closed loop gains The LM363 operates with supply voltages from g 5V to g 18V with only 1 5 mA current drain The LM363’s low voltage noise low offset voltage and offset voltage drift make it ideal for amplifying low-level lowimpedance transducers At the same time its low bias current and high input impedance (both common-mode and differential) provide excellent performance at high impedance levels These features along with its ultra-high common-mode rejection allow the LM363 to be used in the most demanding instrumentation amplifier applications replacing expensive hybrid module or multi-chip designs Because the LM363 is internally trimmed precision external resistors and their associated errors are eliminated The 16-pin dual-in-line package provides pin-strappable gains of 10 100 or 1000 Its twin differential shield drivers eliminate bandwidth loss due to cable capacitance Compensation pins allow overcompensation to reduce bandwidth and output noise or to provide greater stability with capacitive loads Separate output force sense and reference pins permit gains between 10 and 10 000 to be programmed using external resistors On the 8-pin metal can package gain is internally set at 10 100 or 500 but may be increased with external resistors The shield driver and offset adjust pins are omitted on the 8-pin versions The LM363 is rated for 0 C to 70 C Features Y Y Y Y Y Y Y Y Offset and gain pretrimmed 12 nV 0Hz input noise (G e 500 1000) 130 dB CMRR typical (G e 500 1000) 2 nA bias current typical No external parts required Dual shield drivers Can be used as a high performance op amp Low supply current (1 5 mA typ) Typical Connections 16-Pin Package 8-Pin Package G e 10 2 3 4 open G e 100 3–4 shorted G e 1000 2–4 shorted TL H 5609 – 33 TL H 5609 – 1 Connection Diagrams Metal Can Package Order Number LM363H-10 LM363H-100 or LM363H-500 See NS Package Number H08C C1995 National Semiconductor Corporation TL H 5609 16-Pin Dual-In-Line Package TL H 5609 – 2 Order Number 363D See NS Package Number D16C RRD-B30M115 Printed in U S A LM363 Precision Instrumentation Amplifier April 1991
