1 OBSOLETE PRODUCT NO RECOMMENDED REPLACEMENT contact our Technical Support Center at 888TERSIL or HA595 Data Sheet November 9, 2 FN29.6 5MHz, Fast Settling Operational Amplifier The HA595 is a operational amplifier featuring a combination of speed, precision, and bandwidth. Employing monolithic bipolar construction coupled with Dielectric Isolation, this device is capable of delivering 2V/µs slew rate with a settling time of 7ns (.%, 5V output step). This truly differential amplifier is designed to operate at gains 5 without the need for external compensation. Other outstanding features are 5MHz gain bandwidth product and 6.5MHz full power bandwidth. In addition to these dynamic characteristics, this amplifier also has excellent input characteristics such as 3mV offset voltage and 6.nV/ Hz input voltage noise at khz. With 2V/µs slew rate and 7ns settling time, the HA595 is an ideal output amplifier for accurate, high speed D/A converters or the main components in high speed sample/hold circuits. The 595 is also ideally suited for a variety of pulse and wideband video amplifiers. Please refer to Application Notes AN525 and AN526 for some of these application designs. At temperatures above 75 o C a heat sink is required for the HA595 (see Note 2 and Application Note AN556). Part Number Information PART NUMBER TEMP. RANGE ( o C) PACKAGE PKG.

Decoupling capacitors should be located as near to the amplifier terminals as possible. Stability Considerations HA595 is stable at gains > 5. Gains < 5 are covered below. Feedback resistors should be of carbon composition located as near to the input terminals as possible. Output Short Circuit HA595 does not have output short circuit protection. Short circuits to ground can be tolerated for approximately seconds. Short circuits to either supply will result in immediate destruction of the device. Heavy Capacitive Loads When driving heavy capacitive loads (>pf) a small resistor (Ω) should be connected in series with the output and inside the feedback loop. Wiring Considerations Video pulse circuits should be built on a ground plane. Minimum point to point connections directly to the amplifier terminals should be used. When ground planes cannot be used, good single point grounding techniques should be applied. FN29.6 November 9, 2
