The EL2019 offers a new feature previously unavailable in a comparator before—a master/slave edge triggered flip-flop. The comparator output will only change output state after a positive going clock edge is applied. Thus the output cant feed back to the input and cause oscillation.

Features

• Comparator cannot oscillate

• Fast response—5ns data to clock setup, 20ns clock to output

• Wide input differential voltage range—24V on ±15V supplies

• Wide input common mode voltage range—±12V

• Precision input stage—VOS = 1.5mV

• Low input bias current—100nA

• Low input offset current—30nA

• ±4.5V to ±18V supplies

• Three-State TTL compatible output

• No supply current glitch during switching

• 103dB voltage gain (Low input uncertainty ≈ 30µV)

• 50 power reduction in shut-down mode

• Input and flip-flop remain active in shutdown mode

Applications

• Analog to digital converters

• ATE pin receiver

• Zero crossing detector

• Window detector

• “Go/no-go” detector
