7 / 42 page  Q Q D Not Recommended for New Designs LMF100 www.ti.com SNOSBG9B – JULY 1999 – REVISED JUNE 2015 Electrical Characteristics for V + = +2.5 V and V− = −2.5 V (continued) 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.

This is illustrated in the curves under the heading Typical Characteristics. (4) Vos1, Vos2, and Vos3 refer to the internal offsets as discussed in the Application Information. (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. Copyright © 1999–2015, Texas Instruments Incorporated Submit Documentation Feedback 7 Product Folder Links: LMF100 |
