Dual CMOS op-amp in a hermetic 8-CDIP
Supply range spans 4.6 V to 16 V, single or split. The 8-CDIP package provides a hermetic cavity that resists moisture and corrosive atmospheres — a common requirement in avionics and satellite payloads where conformal coating alone is insufficient. The through-hole mounting suits hand-assembly or socketed prototypes in test and instrumentation racks.
Low offset and bias — what they mean for sensor front-ends
An 80 µV input offset and 1 pA bias current let the TLC2202AMJG interface directly with high-impedance sources such as piezoelectric accelerometers, thermocouples, and photodiode amplifiers without a separate buffer. The CMOS input stage keeps self-heating errors negligible. In a precision integrator or charge amplifier, the 1 pA bias translates to less than 1 mV drift over a 1 GΩ feedback resistor at 25°C.
Supply current and output drive
Quiescent supply current is 1.8 mA total for both amplifiers, which keeps the thermal budget manageable even in a sealed ceramic package. The 50 mA per-channel output is enough to drive a twisted-pair line, a small relay coil, or a 100 Ω load to within a volt of the rails.
