Product Description

The PI5A124 are analog switches designed for single-supply operation. These high-precision devices are ideal for low-distortion audio, video, signal switching and routing. These switches are fully specified with +5V, and +3.3V supplies. With +5V, they guarantee <10Ω On-Resistance. On-Resistance matching between channels is within 2Ω. On-Resistance flatness is less than 55Ω over the specified range. These switches also guarantee fast switching speeds (tON <20ns). These products are available in 6-pin SOT23 plastic packages for operation over the industrial (-40oC to +85oC) temperature range.


  • Single-Supply Operation (+2V to +6V)
  • Rail-to-Rail Analog Signal Dynamic Range
  • Low On-Resistance (6Ω typ. with 5V supply) Minimizes Distortion and Error Voltages
  • On-Resistance Flatness, 3Ω typ.
  • Low Charge Injection Reduces Glitch Errors. Q = 4pC typ.
  • High Speed. tON = 10ns typ.
  • Wide -3dB Bandwidth: 326 MHz (typ.)
  • High-Current Channel Capability: >100mA
  • TTL/CMOS Logic Compatible
  • Low Power Consumption (0.5μW typ)
  • Small outline transistor package minimizes board area
  • Packaging (Pb-free & Green available):
    • 6-pin 65-mil wide SOT23 (T) for PI5A124
