† Stresses beyond those listed under "absolute maximum ratings" may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated under "recommended operating conditions" is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
NOTES: 1. All voltage values, except differential voltages, are with respect to VDD /GND.
2. Differential voltages are at IN+ with respect to IN . Excessive current flows when an input is brought below VDD 0.3 V.
3. The output may be shorted to either supply. Temperature and/or supply voltages must be limited to ensure that the maximum dissipation rating is not exceeded.
DescriptionThe TLC4501 and TLC4502 are the highest precision CMOS single supply rail-to-rail operational amplifiers available today. The input offset voltage is 10 mV typical and 40 mV maximum. This exceptional precision, combined with a 4.7-MHz bandwidth, 2.5-V/ms slew rate, and 50-mA output drive, is ideal for multiple applications including: data acquisition systems, measurement equipment, industrial control applications, and portable digital scales.
These amplifiers TLC4501 feature self-calibrating circuitry which digitally trims the input offset voltage to less than 40 mV within the first 300 ms of operation. The offset is then digitally stored in an integrated successive approximation register (SAR). Immediately after the data is stored, the calibration circuitry of TLC4501 effectively drops out of the signal path, shuts down, and the device functions as a standard operational amplifier.
