The OP-15 has the speed of the LF156 design with the low power dissipation of the slower LF155. The OP-16 is considerably faster. Both devices offer offset voltages as low as 0.5mV, with guaranteed drift of 5nV/C. Input bias current at 125C is just a few nanoamperes. Other manufacturers OP-15/16 (and LF155/ 156) ex- hibit phase reversal at the output when the negative common-mode limit at the input is exceeded; i.e., driving from 12V to 15V with +15V supplies. This can cause lock-up in servo systems. As shown in the applica- tion section, Linear Technologys OP-15/16 does not have this problem due to unique phase reversal protec- tion circuitry. In addition, Linears OP-16 is free from high frequency oscillation problems at cold temperatures, as is il- lustrated in the Voltage Follower Small Signal Pulse Response photo. For applications requiring higher performance, see the LT1022, LT1055 and LT1056 data sheets.
