LT1016CH
LT1016CH - 10 ns Precision Comparator | Analog Devices
Analog Devices LT1016CH is an ultra-fast precision comparator with a 10 ns propagation delay, direct TTL/CMOS compatibility, and operation from either ±5 V or a single 5 V supply. It is offered in a 10-pin TO-5 package. The device supports complementary outputs, tight offset-voltage specifications, high gain, and an active drive stage capable of driving logic in both output directions. Its combination of speed, precision, and supply flexibility makes it useful in high-speed instrumentation, pulse and timing systems, threshold detection, and applications requiring predictable logic-level interfacing.
A comparator is an analog-to-digital interface integrated circuit that compares two input voltages and produces a logic-level result indicating their relative state. In the product hierarchy, the LT1016CH is a comparator within the broader amplifier and interface IC family. Unlike an operational amplifier, a comparator is optimized for rapid binary decisions rather than linear signal amplification. The LT1016CH combines this decision function with low propagation delay and compatibility with common TTL and CMOS logic families.
The primary feature of the LT1016CH is its 10 ns response time. This fast transition allows the comparator to resolve input differences with little delay, making it appropriate for pulse-width measurement, zero-cross detection, high-speed thresholding, and timing-reference circuits. The matched complementary outputs allow system designers to use true and inverted logic signals from one device. The manufacturer also specifies tight offset voltage and high gain, supporting precision comparison tasks where input offset can affect the decision point.
The LT1016CH can operate from dual ±5 V rails or a single 5 V supply. This operating flexibility is valuable in legacy instrumentation, laboratory equipment, industrial control systems, and mixed-signal designs where negative input or output signal ranges may be required. Its negative-supply quiescent current is specified as 3 mA, and performance is not affected by variations in negative supply voltage. These characteristics simplify power planning in systems where the negative rail is generated from another supply through a resistive divider.
Typical uses include high-speed edge detection, pulse-width monitoring, window comparison, oscillator timing, overvoltage detection, and threshold circuits feeding TTL or CMOS logic. The complementary outputs can reduce the need for an additional inverter, while the 10 ns delay supports higher event rates than general-purpose comparators. Care should still be taken to control input overdrive, ringing, output loading, and supply bypassing near the device.
For reliable operation, place input and supply bypass capacitors close to the corresponding pins and route high-speed comparator signals over short, controlled-impedance traces. Avoid long unprotected routes between the comparator and receiving logic, and evaluate output behavior with the actual load and supply arrangement. Use the manufacturer pin description and connection diagrams when assigning PCB functions and latch-control logic.
This page organizes the LT1016CH specifications, sourcing information, application guidance, and verified drop-in assessment into a practical engineering reference. It also highlights design constraints that matter beyond the headline 10 ns speed, including supply architecture, complementary-output use, latch control, and high-speed PCB implementation.
