1 / 21 page SL3522 500MHz 75dB Logarithmic/Limiting Amplifier Advance Information The SL3522 is a monolithic seven stage successive detection logarithmic amplifier integrated circuit for use in the 100MHz to 500MHz frequency range. It features an on–chip video amplifier with provision for external adjustment of log Slope and offset. It also features a balanced RF output. The SL3522 operates from supplies of ±5V. FEATURES s 75dB Dynamic Range s Surface Mount SO Package s Adjustable Log Slope and Offset s 0dBm RF Limiting Output s 60dBm Limiting Range s 2V Video Output Range s Low Power (Typ. 1W) s Temperature Range (T CASE): -55°C to +125°C APPLICATIONS s Ultra Wideband Log Receivers s Channelised and Monpulse Radar s Instrumentation ABSOLUTE MAXIMUM RATINGS Supply Voltage ±6.0V Storage temperature -65 °C to +175°C Junction temperature +175 °C Thermal resistance Die-to-case 15.5 °C/W Die-to-ambient 76.5 °C/W Applied DC voltage to RF input ±400mV Applied RF power to RF input +15dBm MC28 Fig.1 Pin connections - top view Fig.2 Functional block diagram ORDERING INFORMATION SL3522 A MC (Miniature Ceramic package) SL3522 C MC (Miniature Ceramic package) SL3522 NA 1C (Probe-tested bare die) (Also available: SL3522 AA MC screened to Zarlink HI-REL level A. Contact Zarlink Semiconductor sales outlet for a separate datasheet.) ESD PROTECTION To achieve the high frequency performance there are no ESD protection structures on the RF input pins (27, 28). These pins are highly static sensitive, typically measured as 250V using MIL-STD-883 method 3015. Therefore, ESD handling precautions are essential to avoid degradation of performance or permanent damage to this device.
