MA 40 Measurement Amplifier The MA40 is a versatile High-Speed Measurement Amplifier for data rates up to 40 Gb/s (OC768/STM256). Key features are: - single-ended and differential I/O operation,
- adjustable input threshold,
- adjustable input bias,
- switchable offset cancellation,
- adjustable output swing,
- DC coupled operation,
- single supply voltage.
 The MA40 has a fully symmetrical differential input buffer. This allows differential as well as single- ended drive and is optimized for 50? line termination. | Parameter
