AT-283-PIN

AT-283-PIN Digital Attenuator 15.5 dB, 5-Bit, TTL Driver, DC-2.0 GHz Features Rev. V7 Functional Schematic  Attenuation: 0.5 dB Steps to 15.5 dB  Temperature Stability: ± 0.18 dB from –55°C to +85°C Typical  Low DC Power Consumption  Hermetic Surface Mount Package  Integral TTL Driver  50 Ω Nominal Impedance  Lead-Free CR-12 Package  260°C Reflow Compatible  RoHS* Compliant Description M/A-COM’s AT-283-PIN is a GaAs FET 5-bit digital attenuator with a 0.5 dB minimum step size and 15.5 dB total attenuation. This attenuator and integral TTL driver is in a hermetically sealed ceramic 16 lead surface mount package. The AT-283-PIN is ideally suited for use where accuracy, fast switching, very low power consumption and low intermodulation products are required. Typical applications include dynamic range setting in precision receiver circuits and other gain/leveling control circuits. Environmental screening is available. Contact the factory for information.

Absolute Maximum +27 dBm +34 dBm VCC -0.5V ≤ VCC ≤ +7.0V VEE -8.5V ≤ VEE ≤ +0.5V VCC - VEE -0.5V ≤ VCC - VEE ≤ 14.5V Vin6 -0.5V ≤ Vin ≤ VCC + 0.5V Operating Temperature -55°C to +125°C Storage Temperature -65°C to +150°C Exceeding any one or combination of these limits may cause permanent damage to this device. M/A-COM does not recommend sustained operation near these survivability limits. Standard CMOS TTL interface, latch-up will occur if logic signal is applied prior to power supply. Handling Procedures Please observe the following precautions to avoid damage: Static Sensitivity Gallium Arsenide Integrated Circuits are sensitive to electrostatic discharge (ESD) and can be damaged by static electricity. Proper ESD control techniques should be used when handling these devices.
