1.1 Introduction

The LMH13000 is a high-speed, output current driver designed for precise and rapid current control, making this device an excellent choice for applications that demand fast and accurate current pulses. With rise and fall times of < 1ns, this device is designed for use in industrial optical sensors, optical time-domain reflectometers (OTDR), high-speed current loads, and medical applications such as in-vitro diagnostics (IVD) and flow cytometry. The device supports continuous currents up to 1A and pulsed currents up to 5A, limited on factors such as frequency, duty cycle, and heat dissipation. The LMH13000 operates within a 3V to 5.5V voltage range, with LVDS inputs enabling precise control over output parameters such as on time, frequency, and duty cycle. These features make this device a reliable, efficient option for high-speed, high-precision current-driving applications.

The LMH13000RQEEVM is designed to evaluate the performance of the LMH13000. The EVM includes SMA connector for all inputs and output pins, and a banana connector for supplies. This user's guide provides device and connector descriptions, a schematic, a bill of materials, and the printed circuit board (PCB) layout.
