Key Features
- 67 dB off-state isolation enabling clean signal routing in precision RF and instrumentation multiplexing applications
- 0.04 Ω on-resistance matching across all 4 channels minimizing channel-to-channel gain error in differential signal paths
- 1.8 V to 5.5 V single-supply operation compatible with modern low-voltage DSP and microcontroller logic levels
- Quad SPST normally-closed configuration in a compact 16-lead LFCSP for high-density switch matrix designs
Applications
The ADG811YCPZ-REEL is used in precision analog switch matrices, automated test equipment (ATE), and medical imaging systems where low on-resistance and high isolation are required simultaneously across multiple signal paths. Its 0.04 Ω resistance matching makes it suitable for gain-critical differential signal routing in instrumentation amplifier front-ends and data acquisition systems sampling at up to 16-bit resolution. The 1.8 V supply compatibility also suits RF baseband switching in software-defined radio and telecommunications equipment running from low-voltage CMOS logic.

Frequently Asked Questions
What off-state isolation does ADG811YCPZ-REEL achieve, and how does it affect crosstalk in an 8-channel ADC multiplexer?
The ADG811YCPZ-REEL achieves 67 dB off-state isolation at 1 MHz. In an 8-channel multiplexer driving a 16-bit ADC, 67 dB isolation means an adjacent channel's full-scale signal of 5 V leaks only about 0.22 mV into the selected channel — below the 0.15 mV LSB size of a 16-bit converter at 5 V full scale, so the switch's isolation is the limiting factor only at frequencies above a few megahertz.
How does the 0.04 Ω on-resistance matching of ADG811YCPZ-REEL benefit differential measurement circuits?
In a 4-wire resistance measurement bridge or differential amplifier front-end, the 0.04 Ω channel-to-channel on-resistance matching of ADG811YCPZ-REEL introduces less than 0.04 Ω imbalance between the two signal paths. With a 10 kΩ source impedance, this corresponds to a differential gain error of 4 ppm, which is negligible for 16-bit data acquisition and eliminates the need to trim or calibrate individual switch resistance at the system level.
At what supply voltage does ADG811YCPZ-REEL operate, and can it interface directly with 1.8 V FPGA I/O banks?
The ADG811YCPZ-REEL supports a single supply from 1.8 V to 5.5 V. At 1.8 V supply, the digital control inputs accept logic-high thresholds of approximately 0.7 x VDD = 1.26 V and logic-low thresholds of 0.3 x VDD = 0.54 V, which are directly compatible with LVCMOS18 I/O banks on Xilinx and Intel FPGAs, enabling direct control without voltage-level translation circuitry.
What package does ADG811YCPZ-REEL use, and how does its footprint compare to a traditional SOIC-16?
The ADG811YCPZ-REEL uses a 16-lead LFCSP (4 mm x 4 mm body) with 0.5 mm lead pitch, occupying roughly 16 mm² of PCB area. A standard SOIC-16 footprint measures approximately 10 mm x 4 mm, or 40 mm² — about 2.5 times larger. The LFCSP's smaller footprint and exposed thermal pad make it better suited to high-density analog switch arrays on compact PCBs where multiple ADG811 devices must be placed near signal connectors.
