Description :

The LM111, LM211, LM311J-8 and LM311 are voltage comparators that have input currents nearly a thousand times lower than devices like the LM106 or LM710. They are also designed to operate over a wider range of supply voltages: from standard ±15V op amp supplies down to the single 5V supply used for IC logic. Their output is compatible with RTL, DTL and TTL as well as MOS circuits. Further, they can drive lamps or relays, switching voltages up to 50V at currents as high as 50 mA.

Both the inputs and the outputs of the LM111, LM211 or the LM311 can be isolated from system ground, and the output can drive loads referred to ground, the positive supply or the negative supply. Offset balancing and strobe capability are provided and outputs can be wire OR’ed. Although slower than the LM106 and LM710 (200 ns response time vs 40 ns) the devices are also much less prone to spurious oscillations. The LM111 has the same pin configuration as the LM106 and LM710.

Features

1. Operates from single 5V supply
2. Input current: 150 nA max. over temperature
3. Offset current: 20 nA max. over temperature
4. Differential input voltage range: ±30V
5. Power consumption: 135 mW at ±15V

AD8561 Datasheet – Single Supply Comparator ( PDF )

Part Number : AD8561

Function : Ultrafast 7 ns Single Supply Comparator

Package : SOIC, DIP, TSSOP 8 Pin Type

Manufacturers : Analog Devices

AD8561 datasheet

 

Description :

The AD8561 is a single 7 ns comparator with separate input and output sections. Separate supplies enable the input stage to be operated from ±5 V dual supplies and +5 V single supplies.

Propagation delays for rising and falling signals are closely matched and track over temperature. This matched delay makes the AD-8561 a good choice for clock recovery, since the duty cycle of the output will match the duty cycle of the input.

Features :

1. 7 ns Propagation Delay at 5 V
2. Single Supply Operation : 3 V
3. Latch Function

Applications :

1. High Speed Timing
2. Clock Recovery and Clock Dis
3. Line Receivers
4. Digital Communications
5. Phase Detectors
6. High Speed Sampling
7. Read Channel Detection
8. Upgrade for LT1016 Designs
