APPLICATION INFORMATION
The key operational-amplifier parameters CMRR, PSRR, and offset drift were optimized to achieve superior
offset performance. The TLC4502 calibration DAC is implemented by a binary-weighted current array using a
pseudo-R-2R MOSFET ladder architecture, which minimizes the silicon area required for the calibration
circuitry, and thereby reduces the cost of the TLC4502.
Due to the performance (precision, PSRR, CMRR, gain, output drive, and ac performance) of the TLC4502, it
is ideal for applications like:
D Data acquisition systems
D Medical equipment
D Portable digital scales
D Strain gauges
D Automotive sensors
D Digital audio circuits
D Industrial control applications
It is also ideal in circuits like:
D A precision buffer for current-to-voltage converters, a/d buffers, or bridge applications
D High-impedance buffers or preamplifiers
D Long term integration
D Sample-and-hold circuits
D Peak detectors
The TLC4502 self-calibrating operational amplifier is manufactured using Texas instruments LinEPIC process
technology and is available in an 8-pin SOIC (D) Package. The C-suffix devices are characterized for operation
from 0°C to 70°C. The I-suffix devices are characterized for operation from –40°C to 125°C. The M-suffix
devices are characterized for operation from –55°C to 125°C.
