1 L T1010 1010fc Fast ± 150mA Power Buffer The LT ® 1010 is a fast, unity-gain buffer that can increase the output capability of existing IC op amps by more than an order of magnitude. This easy-to-use part makes fast amplifiers less sensitive to capacitive loading and reduces thermal feedback in precision DC amplifiers.
