8 The TLC2652 and TLC2652A are high-precision chopper-stabilized operational amplifiers using FK PACKAGE Texas Instruments Advanced LinCMOS (TOP VIEW) process. This process, in conjunction with unique chopper-stabilization circuitry, produces opera tional amplifiers whose performance matches or exceeds that of similar devices available today. Chopper-stabilization techniques make possible NC 18 CLK OUT 4 extremely high dc precision by continuously NC 5 nulling input offset voltage even during variations 16 VDD 6 in temperature, time, common-mode voltage, and NC 7 power supply voltage. In addition, low-frequency 14 OUT IN + noise voltage is significantly reduced. This high precision, coupled with the extremely high input impedance of the CMOS input stage, makes the TLC2652 and TLC2652A an ideal choice for low-level signal processing applications such as strain gauges, thermocouples, and other transducer amplifiers. For applications that No internal connection require extremely low noise and higher usable bandwidth, use the or TLC2654A device, which has a chopping frequency of 10 kHz. The TLC2652 and TLC2652A input common-mode range includes the negative rail, thereby providing superior performance in either single-supply or split-supply applications, even at power supply voltage levels as low 1.9 V. Two external capacitors are required for operation of the device; however, the on-chip chopper-control circuitry is transparent to the user. On devices in the 14-pin and 20-pin packages, the control circuitry is made accessible to allow the user the option of controlling the clock frequency with an external frequency source. In addition, the clock threshold level of the TLC2652 and TLC2652A requires no level shifting when used in the single-supply configuration with a normal CMOS or TTL clock input. 7 Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.

Innovative circuit techniques are used on the TLC2652 and TLC2652A to allow exceptionally fast overload recovery time. If desired, an output clamp pin is available to reduce the recovery time even further. The device inputs and output are designed to withstand 100-mA surge currents without sustaining latch-up. Additionally the TLC2652 and TLC2652A incorporate internal ESD-protection circuits that prevent functional failures at voltages V as tested under MIL-STD-883C, Method 3015.2; however, care should be exercised in handling these devices, as exposure to ESD may result in degradation of the device parametric performance. The C-suffix devices are characterized for operation from to 70°C. The I-suffix devices are characterized for operation from to 85°C. The Q-suffix devices are characterized for operation from 40°C to125°C. The M-suffix devices are characterized for operation over the full military temperature range 55°C to125°C.
