TLV3501 Multifunctional Voltage Comparator

This project integrates a TLV3501 voltage comparator and a simple non-inverting amplifier circuit based on the LMH6609.
 
 
Relevant parameters
: Power supply voltage: ±3.3-5VDC; Input voltage: 10-2400mV (amplitude, 5V supply); Output level: Rail-to-rail output, can directly drive TTL/CMOS levels; Input frequency: DC–200MHz (experimentally ideal below 100MHz); All interface types: SMA female connector (external screw, internal hole); Comparator input impedance: 51 ohms;
Voltage comparator module modes: 1. Non-inverting zero-crossing comparator: H4, H3, H1 closed; 2. Inverting zero-crossing comparator: H4, H3, H2 closed; 3. Two-input comparator: H3, H4 closed; 4. Non-inverting comparator (adjustable comparison voltage): H4, H6 closed, adjust R7 to control the comparison voltage, measurable at H9. 5. Inverting comparison (adjustable comparison voltage): H3 and H7 are closed, and R7 is adjusted to control the comparison voltage. It can be measured at H9. 6. Hysteresis comparison: H4, H3, and H8 are connected, and R5 is adjusted to control the size of the hysteresis window.
