ADG736BRMZ Dual-Channel SPDT CMOS Analog Switch | Low Power Consumption, Low Distortion, High-Speed Switching

Introduction

The ADG736 operates from a single 1.8 V to 5.5 V supply,making it ideally suited to portable and battery-powered instruments.The on resistance profile is very flat over the full analog signal range. This ensures excellent linearity and low distortion when switching audio signals. Fast switching speed also makes the part suitable for video signal switching.Each switch conducts equally well in both directions when on, and each has an input signal range that extends to the power supplies.The ADG736 exhibits break-before-make switching action.

PIN CONFIGURATION AND FUNCTION DESCRIPTIONS

How ADG736 can reliably switch analog signals under low power consumption, high linearity and high speed conditions

1. The ADG736 features a CMOS design, which inherently delivers ultra-low static power consumption. Its switching current remains minimal during both on and off states, ensuring minimal battery drain even during prolonged operation. This low-power architecture enables stable operation across 1.8V to 5.5V single-supply systems without generating additional heat or power overhead.
2. The small variation of the on-resistance of ADG736 in the signal range makes the analog signal not distorted when passing through the switch. Meanwhile, the switch will not introduce obvious noise or nonlinear distortion because of the flat RON and low drain current, and each switch can transmit signal bidirectionally.
3. The ADG736 has a short switching response time of just a few nanoseconds, allowing for rapid switching of analog signals. Additionally, the ADG736's Break-before-Make prevents short circuits or signal conflicts, enhancing switching reliability. The wide bandwidth supports high-speed signals, ensuring stable operation in 1.8V~5.5V systems and maintaining the integrity of high-speed analog signals during switching.

Conclusion

Why ADG736 over alternatives? Its low on-resistance ensures analog signal linearity and minimal distortion, while its wide bandwidth handles high-frequency signals. With an adaptable wide power supply range and excellent temperature tolerance, it operates reliably in industrial and demanding environments. The ADG736 also delivers low leakage current, minimal distortion, and a compact package.
All these factors make the ADG736 a reliable choice for portable devices, precision measurement equipment, or space-sensitive miniaturized applications.
