Novel input stage design of this amplifier provides extremely high slew rates in pulse applications while maintaining low quiescent current of under 1mA. This novel input stage also has the effect of adding variables to the power response and slew rate characteristics of the amplifier. To a lesser degree, there are also input related effects on open loop gain and phase. It is important to note that slew rate for the PA69 is independent of supply current. However the slew rate is a strong function of input voltage amplitude. It should be noted that the package tab needs to be connected to a stable reference such as GND for high slew rates. Please refer to special considerations section for details. The output stages are well protected with user defined current limit although the Safe Operating Area (SOA) must be observed for reliable protection. Proper heatsinking is required for maintaining maximum reliability. External phase compensation provides the user with great flexibility in trading gain, stability and bandwidth.

The deflection amplifier shown above achieves accurate droplet displacement at high speeds to deposit crisp, clear lot code information on product containers. The external compensation networks have been optimized to match the gain of the circuit and the complex impedance of the load. The combination of high voltage and high speed allow repeatable low cost deflection of droplets for high production environments.

Visit www.apexmicrotech.com for design tools that help automate tasks such as calculations for stability, internal power dissipation, current limit, heat sink selection, Apex’s complete Application Notes library, Technical Seminar Workbook and Evaluation Kits. Bypass capacitors to power supply terminals +Vs and –Vs must be connected physically close to the pins to prevent local parasitic oscillation in the output stage of the PA69. Use electrolytic capacitors at least 1μF. Bypass the electrolytic capacitors with high quality ceramic capacitors (X7R) 0.1μF or greater. SPECIAL CONSIDERATIONS It is very important to realize that in order to achieve high frequency performance the heat sink tab has to be tied to a stable, low impedance reference, i.e. power supply or GND. An AC connection through a 0.1µF capacitor is also sufficient. Internal to the PA69, the heatsink tab is electrically isolated to more than 350V . This may help allay some electrical isolation concerns in tying the heat sink to Vs or GND. CURRENT LIMIT For proper operation, the current limit resistor, Rlim, must be connected as shown in the external connections diagram. For maximum reliability and protection, the resistor should be set as high as possible. The value of the resistor is calculated as follows, with Ilim in A; the maximum practical value is 1500Ω. Rlim = 0.7 / Ilim SUPPLY CURRENT The PA69 features a class A/B driver stage to drive the output MOSFETs and an innovative input stage to achieve very high slew rates. The supply current drawn by the PA69, even with no load, varies with the slew rate of the output signal. The PA69 is externally compensated and performance can be tailored to the application. Use the graphs of small signal response and power response as a guide. Due to the innovative design of the PA69, two compensation networks are required. The values of these components should be the same to provide symmetric slew rate characteristics. The compensation capacitor Cc must be rated at 500V working voltage. NPO capacitors are recommended. The compensation networks CcRc must be mounted closely to the amplifier pins x & y and z & w to avoid spurious oscillation. The PA69 may require an external 33 pF capacitor (minimum breakdown of 200 V) between CC- (pin 3) and –Vs (pin 5) to prevent oscillations in the falling edge of the output. This capacitor is provided with the evaluation kit. Please refer to EK60 datasheet for details. A N I M I L SAFE OPERATING AREA Y R STABILITY The MOSFET output stage of the PA69 is not limited by second breakdown considerations as in bipolar output stages. Only thermal considerations and current handling capabilities limit the SOA. The output stage is protected against transient flyback by the parasitic body diodes of the output stage MOSFET structure. However, for protection against sustained high energy flyback external fast-recovery diodes must be used.
