What are the key features of ADG852?
- Ultra-low 0.8 Ω on-resistance minimizes signal attenuation and power loss in switched analog paths
- Wide 1.8 V to 5.5 V single-supply operation covers both 1.8 V low-power and 5 V industrial logic domains
- Miniature LFCSP (Quad Flat No-Lead) package enables compact PCB layouts in portable and wearable devices
What is ADG852 used for?
The ADG852 is ideal for routing audio and RF signals in portable consumer electronics, battery-powered medical instruments, and handheld test equipment where the 1.8 V minimum supply and 0.8 Ω on-resistance preserve signal integrity. Its SPDT/2:1 mux topology is also widely used in communication systems for antenna switching, clock source selection, and I2C bus multiplexing in multi-sensor IoT nodes.

Frequently Asked Questions
What on-resistance does the ADG852 offer, and why does it matter for analog signal routing?
The ADG852 has a typical on-resistance of 0.8 Ω, which is among the lowest available in CMOS SPDT switches. This low resistance reduces the voltage drop across the switch at signal currents in the milliamp range and minimizes thermal noise insertion, making it suitable for precision analog paths, audio signal routing, and sensor measurement chains where even a few ohms of series resistance would degrade accuracy.
Can ADG852 operate directly from a 1.8 V microcontroller power rail in an IoT design?
Yes. The ADG852 operates from a single supply as low as 1.8 V, which matches the I/O voltage of most modern low-power microcontrollers and application processors. This allows direct logic-level control of the switch without level-shifting circuitry, reducing BOM cost and keeping the active current consumption well below 1 µA in standby, important for battery life in IoT edge nodes.
How does ADG852 in LFCSP compare to ADG836 for a dual-switch requirement in a space-limited layout?
The ADG852 is a single SPDT switch in a miniature LFCSP measuring approximately 1 mm × 1.5 mm, while the ADG836 integrates 2 SPDT switches for dual-channel routing. If 2 independent switched paths are needed and board area below 4 mm² is critical, the ADG836 is more efficient; for a single-path application with the tightest possible footprint, the ADG852 at 0.8 Ω on-resistance and 1.8 V minimum supply remains the optimal choice.
