Frequently Asked Questions (FAQ)
When legacy DG403DY stock finally runs out, is it safer to cross to Maxim MAX4622ESE+ or Vishay DG403DYZ-T for low-leakage picoammeter front-ends, and what guard-ring tweaks are needed?
DG403DY is already flagged obsolete, so MAX4622ESE+ actually keeps you closest to its 500 pA / 85 °C spec. DG403DYZ-T is a lead-free, same-die revision; its 300 pA max room-temp leakage looks better on paper, but the SOIC-16 body’s moisture-induced drift can hit 2 nA above 60 °C unless you run Kelvin guard traces around pins 3, 7, 10, 14 and conformal-coat with parylene-C. If your product must be >10 yr serviceable, socket MAX4622ESE+ in a gold-plated machined socket so future buyers can drop in newer parts without board rework.
I’m squeezing two DG403DY switches into 4 mm² 36 V sensor rails; how much derating is realistic for ±22 V bipolar supplies to avoid EOS when inductive load kickback reaches 45 V?
DG403DY abs-max is only ±22 V, so inductive flyback must be clamped below 25 V. Add a 22 V, 500 mW bidirectional TVS (SMAJ22CA) across each pole, keep clamp loop area <2 cm², and stage a 33 Ω series snubber. Expect on-resistance to climb from 45 to ~55 Ω at cold start—compensate by trimming the current-sense resistor so your 4-20 mA loop stays within 0.1 % even at −40 °C.
Swapping from DG403DY to MAX4622CSE+ in a 16-bit audio summing network, will the extra 15 pF off-capacitance blow my THD budget when channels are muted?
DG403DY gives 12 pF off-C, MAX4622CSE+ lists 27 pF; at 20 kHz that injects only −102 dB crosstalk, below the DG403DY 90 dB you already have. Real danger is the RC pole formed with your 10 kΩ summing resistor—move R to 2.2 kΩ and add an OPA1611 buffer so the added 15 pF costs less than 0.0003 % THD, well under 16-bit floor.
If I parallel two DG403DY dies to halve the 45 Ω RON for 50 Ω RF paths, can their 3 Ω ΔRon mismatch create a reflection bigger than −30 dB at 30 MHz?
A 3 Ω step inside 50 Ω gives a 0.06 ρ, i.e. −24 dB reflection—fail for most VSWR masks. Cure: after paralleling, add a 10 Ω, 0603 thin-film series resistor at each DG403DY output so your worst-case mismatch is now 1.5 Ω/60 Ω, dropping ρ to 0.025 (−32 dB). Keep traces <1 cm, ground plane uninterrupted under the pair, and stagger 10 nF supply decouplers to avoid hot-spot current sharing that could push one switch into thermal runaway.
DG403DY ESD rating isn’t listed—will swapping to DG403DY+ solve hand-assembly HBM risk in a dry-Arizona facility where we already see 4 kV walking-wounded failures on the old DG403DY?
The original DG403DY die predates modern ESD cells; unlisted HBM is typically <1 kV. DG403DY+ (standard “+” suffix) ships with 2 kV HBM, still marginal for your 4 kV line. Keep the new part, but force assemblers to wear wrist straps tested <50 Ω, and place a 100 Ω series input resistor plus a low-capacitance ESD diode (PESD5V0X1B, 0.3 pF) on every exposed pole. That moves survival to 8 kV while only adding 0.3 dB insertion loss at 1 MHz.
