SY2160 vs SY2162: Choosing a 16-Ch HV Analog Switch

16-channel HV analog switches are the common entry point for probe channel expansion. Synergy offers two clear paths:

• SY2160 — 16-ch SPST aligned with traditional HV-rail architectures (ECN3297TF / HV2701 class)
• SY2162 / SY2162QF — 16-ch SPST with +5V-centric control, bleed resistors, low charge injection

Pick by power architecture

If the board already assumes classic HV supplies and HV2701-like footprints, start with SY2160. If you want simpler control-side supplies and bleed-resistor noise control, evaluate SY2162QF.

SY2162QF highlights

• ~0 to ±100V signal range; 16 channels; ~40kΩ bleed resistors
• ~50MHz shift clock; 5V CMOS logic
• Low crosstalk / parasitics; thermal protection
• 48-LQFP 7×7mm

Six questions before lock

1. Signal voltage vs TX peak
2. Ron / flatness vs distortion
3. Charge injection & off-isolation vs RX noise
4. Serial timing vs FPGA
5. Package / creepage / thermal
6. Pin-to-pin proximity to incumbent import P/N

Summary

Choose SY2160 vs SY2162QF by supply architecture first, then qualify injection, isolation, interface and package—scale to 32/64-ch parts when needed.
