General Description

The LMH6732 is a high speed op amp with a unique combination of high performance, low power consumption, and flexibility of application. The supply current is adjustable, over a continuous range of more than 10 to 1, with a single resistor, R_P. This feature allows the device to be used in a wide variety of high performance applications including device turn on/ turn off (Enable/ Disable) for power saving or multiplexing. Typical performance at any supply current is exceptional. The LMH6732's design has been optimized so that the output is well behaved, eliminating spurious outputs on "Enable".

The LMH6732's combination of high performance, low power consumption, and large signal performance makes it ideal for a wide variety of remote site equipment applications such as battery powered test instrumentation and communications gear. Other applications include video switching matrices, ATE and phased array radar systems.

The LMH6732 is available in the SOIC and SOT23-6 packages. To reduce design times and assist in board layout, the LMH6732 is supported by an evaluation board.

Reliability Metrics

Part Number	Process	EFR Sample Size	LTA Device Hours	FITS	MTTF (Hours)
LMH6732MA	VIP 10	12801	1155000	4	327734403

Note: The Early Failure Rates (EFR) were calculated as point estimate PPM based on rejects and sample size for EFR. The Long Term Failure Rates were calculated at 60% confidence using the Arrhenius equation at 0.7eV activation energy and derating the assumed stress temperature of 150°C to an application temperature of 55°C.
