LTC1051/LTC1053 Dual/Quad Precision Zero-Drift Operational Amplifiers With Internal Capacitors FEATURES DESCRIPTIO Dual/Quad Low Cost Precision Op Amp The LTC 1051/LTC1053 are high performance, low cost No External Components Required dual/quad zero-drift operational amplifiers. The unique Maximum Offset Voltage: 5V achievement of the LTC1051/LTC1053 is that they integrate Maximum Offset Voltage Drift: 0.05V/C on chip the sample-and-hold capacitors usually required Low Noise 1.5V (0.1Hz to 10Hz) externally by other chopper amplifiers. Further, the P-P Minimum Voltage Gain: 120dB LTC1051/LTC1053 offer better combined overall DC and Minimum PSRR: 120dB AC performance than is available from other chopper Minimum CMRR: 114dB stabilized amplifiers with or without internal sample/hold Low Supply Current: 1mA/Op Amp capacitors. Single Supply Operation: 4.75V to 16V The LTC1051/LTC1053 have an offset voltage of 0.5V, Input Common Mode Range Includes Ground drift of 0.01V/C, DC to 10Hz, input noise voltage typically Output Swings to Ground 1.5V and typical voltage gain of 140dB. The slew rate P-P Typical Overload Recovery Time: 3ms of 4V/s and gain bandwidth product of 2.5MHz are Pin Compatible with Industry Standard Dual and achieved with only 1mA of supply current per op amp. Quad Op Amps U Overload recover times from positive and negative APPLICATIO S saturation conditions are 1.5ms and 3ms respectively, about a 100 or more times improvement over chopper Thermocouple Amplifiers amplifiers using external capacitors. Electronic Scales Medical Instrumentation The LTC1051 is available in an 8-lead standard plastic Strain Gauge Amplifiers dual-in-line package as well as a 16-pin SW package. The High Resolution Data Acquisition LTC1053 is available in a standard 14-pin plastic package DC Accurate R C Active Filters and an 18-pin SO. The LTC1051/LTC1053 are plug in replacements for most standard dual/quad op amps with , LTC and LT are registered trademarks of Linear Technology Corporation. improved performance.
