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:

It is also ideal in circuits like:

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.
