6 / 42 page  Not Recommended for New Designs LMF100 SNOSBG9B – JULY 1999 – REVISED JUNE 2015 www.ti.com Electrical Characteristics for V + = +5 V and V− = −5 V (continued) The following specifications apply for Mode 1, Q = 10 (R1 = R3 = 100 k, R2 = 10 k), V + = +5 V and V− = −5 V unless otherwise specified. All limits are TA = TJ = 25°C unless otherwise specified.

The crosstalk is the ratio between the output of the grounded filter section and the 1 VRMS input signal of the other section. (6) In 50:1 mode the output noise is 3 dB higher. (7) In 50:1 mode the clock feed through is 6 dB higher. (8) The short circuit source current is measured by forcing the output that is being tested to its maximum positive voltage swing and then shorting that output to the negative supply. The short circuit sink current is measured by forcing the output that is being tested to its maximum negative voltage swing and then shorting that output to the positive supply. These are the worst case conditions. 6.6 Electrical Characteristics for V + = +2.5 V and V− = −2.5 V The following specifications apply for Mode 1, Q = 10 (R1 = R3 = 100 k, R2 = 10 k), V + = +2.50 V and V− = −2.50 V unless otherwise specified. All limits are TA = TJ = 25°C unless otherwise specified.
