PRODUCT DESCRIPTION
The AD810 is a composite and HDTV compatible, current feedback, video operational amplifier, ideal for use in systems such as multimedia, digital tape recorders and video cameras. The 0.1 dB flatness specification at bandwidth of 30 MHz (G = +2) and the differential gain and phase of 0.02% and 0.04° (NTSC) make the AD810 ideal for any broadcast quality video system. All these specifications are under load conditions of 150 (one 75 back terminated cable). The AD810 is ideal for power sensitive applications such as video cameras, offering a low power supply current of 8.0 mA max. The disable feature reduces the power supply current to only 2.1 mA, while the amplifier is not in use, to conserve power. Furthermore the AD810 is specified over a power supply range of ± 5 V to ± 15 V. The AD810 works well as an ADC or DAC buffer in video systems due to its unity gain bandwidth of 80 MHz. Because the AD810 is a transimpedance amplifier, this bandwidth can be maintained over a wide range of gains while featuring a low noise of 2.9 nV/Hz for wide dynamic range applications.

NOTES 1 See Analog Devices Military Data Sheet for 883B Specifications. 2 Slew rate measurement is based on 10% to 90% rise time with the amplifier configured for a gain of 10. 3 Voltage Swing is defined as useful operating range, not the saturation range. 4 Disable guaranteed break before make. 5 Turn On Time is defined with ± 5 V supplies using complementary output CMOS to drive the disable pin. Specifications subject to change without notice.

NOTES 1 Stresses above those listed under "Absolute Maximum Ratings" may cause permanent damage to the device. This is a stress rating only and functional operation of the device at these or any other conditions above those indicated in the operational section of this specification is not implied. Exposure to absolute maximum raring conditions for extended periods may affect device reliability. 2 8-Pin Plastic Package: JA = 90°C/Watt; 8-Pin Cerdip Package: JA = 110°C/Watt; 8-Pin SOIC Package: JA = 150°C/Watt.
ABSOLUTE MAXIMUM RATINGS 1
MAXIMUM POWER DISSIPATION
The maximum power that can be safely dissipated by the AD810 is limited by the associated rise in junction temperature. For the plastic packages, the maximum safe junction temperature is 145°C. For the cerdip package, the maximum junction temperature is 175°C. If these maximums are exceeded momentarily, proper circuit operation will be restored as soon as the die temperature is reduced. Leaving the device in the "overheated" condition for an extended period can result in device burnout. To ensure proper operation, it is important to observe the derating curves.

ESD SUSCEPTIBILITY
AMBIENT TEMPERATURE °C
ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 volts, which readily accumulate on the human body and on test equipment, can discharge without detection. Although the AD810 features ESD protection circuitry, permanent damage may still occur on these devices if they are subjected to high energy electrostatic discharges. Therefore, proper ESD precautions are recommended to avoid any performance degradation or loss of functionality.

Maximum Power Dissipation vs. Temperature
While the AD810 is internally short circuit protected, this may not be sufficient to guarantee that the maximum junction temperature is not exceeded under all conditions.
