NOTES: 2. Above 250 kHz, the input clock duty cycle should be 50% to allow the operational amplifiers the maximum time to settle while processing analog samples. 5. The frequency responses at f are referenced to a dc gain of 0 dB. 6. The dynamic range is referenced to 1.06 V rms (1.5 V peak) where the wideband noise over a 30-kHz bandwidth is typically 106 µV rms for the TLC04/MF4A-50 and 135 µV rms for the TLC14/MF4A-100. operating characteristics over recommended operating free-air temperature range, VCC+ = 5 V, VCC– = –5 V (unless otherwise noted) PARAMETER TEST CONDITIONS TLC04/MF4A-50 TLC14/MF4A-100 UNIT PARAMETER TEST CONDITIONS MIN TYP† MAX MIN TYP† MAX UNIT Maximum clock frequency, fmax See Note 2 2 4 2 4 MHz Clock-to-cutoff-frequency ratio (fclock/fco) fclock ≤ 250 kHz, TA = 25°C 49.58 49.98 50.38 99 100 101 Hz/Hz Temperature coefficient of clock-to-cutoff frequency ratio fclock ≤ 250 kHz ±15 ±15 ppm/ °C fco = 5 kHz, f lk 250 kHz f = 6 kHz – 7.9 – 7.57 – 7.1 dB Frequency response above and below fclock = 250 kHz, TA = 25°C f = 4.5 kHz – 1.7 – 1.44 – 1.3 dB qy cutoff frequency (see Note 5) fco = 5 kHz, f lk 250 kHz f = 3 kHz – 7.9 – 7.42 – 7.1 dB fclock = 250 kHz, TA = 25°C f = 2.25 kHz – 1.7 –1.51 – 1.3 dB Dynamic range (see Note 6) TA = 25°C 86 84 dB Stop-band frequency attentuation at 2 fco fclock ≤ 250 kHz 24 25 24 25 dB Voltage amplification, dc fclock ≤ 250 kHz, RS ≤ 2 kΩ – 0.15 0 0.15 – 0.15 0 0.15 dB Peak-to-peak clock feedthrough voltage TA = 25°C 7 7 mV † All typical values are at TA = 25°C.
