CS59201GDR8

Special Purpose Amplifiers Overview

The CS59201GDR8 is a Winchester servo preamplifier designed for ferrite heads, featuring differential input and output with a fixed gain of approximately 100 V/V. It operates from standard supply voltages of 8.3 V, 10 V, or 12 V (VCC – VEE range: 7.45 V to 13.2 V). The device provides a bandwidth of 50 MHz at 3 dB and draws a typical power supply current of 20 mA. It includes low noise characteristics with an equivalent input noise of 0.7 nV/√Hz and is housed in an SO-8 package.

Special Purpose Amplifiers Procurement Notes

Verify the specific ordering suffix required for your packaging needs. The GDR8 suffix indicates tape and reel packaging containing 2500 units per reel. Confirm that the component meets RoHS compliance standards if applicable to your manufacturing requirements. Ensure compatibility with the specified operating temperature range of 0°C to 70°C during system design.

Special Purpose Amplifiers Selection Notes

Select this component when a low-noise, differential preamplifier is required for ferrite head interfaces. It is suitable for designs needing a fixed gain around 100 V/V and operation from standard 8.3 V, 10 V, or 12 V supplies. Consider the SO-8 package constraints and thermal resistance values for proper heat dissipation in the final assembly.
