Part Name(s) : PCO-6130
Directed-Energy
Directed Energy, Inc. An IXYS Company
Description : PULSED/CW LASER Diode DRIVER MODULE

The PCO-6130 is a compact, OEM-style high power pulsed current source designed to drive Diode lasers, bars and arrays in pulsed, QCW or CW modes. It delivers output current Variable from 1A to 125A, pulse widths Variable from <600ns to DC, and pulse repetition frequencies Variable from single-shot to 250KHz at duty cycles up to 100%.

The PCO-6130 features a user-adjustable Variable rise time control. This innovative feature allows the user to adjust the rise time within a range of <200ns to >5µs by means of a PCB-mounted potentiometer, to optimize the driver’s rise time for the user’s application.

The PCO-6130 is based on a hysteretic, average current, switch-mode regulator. This type of regulator is a Variable frequency, Variable pulse width design which maintains current in an energy storage inductor between a minimum and maximum level. The ripple is limited to the minimum and maximum current determined by the hysteretic controller. The regulator is started when the TTL "enable" line is taken high and runs as long as the enable is high. The use of the hysteretic regulator provides a large input range and high efficiency.

Description : Dual, Ultralow Noise Variable Gain Amplifier

GENERAL DESCRIPTION

The AD604 is an ultralow noise, very accurate, dual-channel, linear-in-dB Variable gain amplifier (VGA) optimized for time based Variable gain control in ultrasound applications; however, it supports any application requiring low noise, wide bandwidth, Variable gain control. Each channel of the AD604 provides a 300 kΩ input resistance and unipolar gain control for ease of use. User-determined gain ranges, gain scaling (dB/V), and dc level shifting of output further optimize performance.

Each channel of the AD604 uses a high performance preamplifier that provides an input-referred noise voltage of 0.8 nV/√Hz. The very accurate linear-in-dB response of the AD604 is achieved with the differential input exponential amplifier (DSX-AMP) architecture. Each of the DSX-AMPs comprises a Variable attenuator of 0 dB to 48.36 dB followed by a high speed fixed gain amplifier. The attenuator is a 7-stage R-1.5R ladder network. The attenuation between tap points is 6.908 dB and 48.36 dB for the ladder network.
