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.

(5)
Crosstalk between the internal filter sections is measured by applying a 1 VRMS 10-kHz signal to one bandpass filter section input and
grounding the input of the other bandpass filter section. 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
