Overview
The EL2142CS-T7 is a high-speed differential amplifier manufactured by Elantec, now part of Renesas Electronics. It features a gain-bandwidth product of 200 MHz and a -3dB bandwidth of 150 MHz. The device operates with a supply voltage range of 6 V to 12.6 V, drawing 11 mA of supply current. Key electrical specifications include a slew rate of 400V/µs, an input offset voltage of 10 mV, and an input bias current of 6 µA. It provides an output current of 60 mA per channel and functions within a temperature range of -40°C to 85°C.
Feature Summary
- High-speed differential amplification with a 200 MHz gain-bandwidth product
- Fast transient response characterized by a 400V/µs slew rate
- Precision input stage with low offset voltage and bias current
- Capable of driving loads with up to 60 mA output current
Applications
- High-speed signal processing circuits
- Video signal conditioning and buffering
- Precision instrumentation front-ends
- Data acquisition systems requiring fast settling
Procurement Notes
Verify component authenticity as the EL2142CS-T7 is discontinued. Confirm that the T7 suffix indicates tape-and-reel packaging if required for automated assembly. Check for RoHS compliance status, as original versions may not meet current environmental standards. Ensure the replacement source provides valid datasheets matching the Elantec/Renesas specifications.
Selection Notes
Select this component when a differential amplifier with high bandwidth and fast slew rate is required. The 200 MHz GBWP supports applications needing rapid signal changes. Consider the 60 mA output drive capability for low-impedance loads. Verify that the 8-SOIC package fits the board layout constraints and that the operating temperature range meets system requirements.
Part Context
The EL2142 series belongs to Elantec's portfolio of high-performance analog integrated circuits, later acquired by Renesas Electronics. This specific model is a single-channel differential amplifier designed for precision and speed. The 'T7' suffix typically denotes tape-and-reel packaging for surface-mount technology, distinguishing it from tube-packaged variants like the EL2142CS.
Replacement Considerations
Public confirmed substitute: AD8015ARZ-REEL7 (Analog Devices Inc.). Verify pinout compatibility and electrical parameter alignment before integration.
