RT9167-50CB(AS) Price NOTES: 1. Input voltages may exceed supply voltages, provided input current is limited to +100.A. 2. Dissipation rating assumes device is mounted with all leads soldered to printed circuit board. 3. Unless otherwise noted, specifications apply at TA = +25YC, fCLOCK = 48 kHz. TC7116/TC7116A and TC7117/TC7117A are tested in the circuit of Figure l. 4. Refer to "Differential Input" discussion. 5. Backplane drive is in-phase with segment drive for "OFF" segment, 180Yout-of-phase for "ON" segment. Frequency is 20 times conversion rate. Average DC component is less than 50 mV. 6. The TC7116/TC7116A logic inputs have an internal pull-down resistor connected from HLDR, pin l to TEST, pin 37. The TC7117/TC7117A logic inputs have an internal pull-down resistor connected from HLDR, pin l to GND, pin 21. RT9167-50CB(AS) on stock OP AMP PERFORMANCE JFET VERSUS BIPOLAR The AD745 0ffers the low input voltage noise of an industry standard bipolar opamp without its inherent input current errors. This is demonstrated in Figure 3, which compares input voltage noise vs. input source resistance of the OP37 and the AD745 0pamps. From this figure, it is clear that at high source impedance the low current noise of the AD745 also provides lower total noise. It is also important to note that with the AD745 this noise reduction extends all the way down to low source impedances. The lower dc current errors of the AD745 also reduce errors due to offset and drift at high source impedances (Figure 4).
