Calculators
Interactive calculation tools for analog filters, op-amp stages, ADC input chains, EMI tasks, thermal checks, crystals and component selection. They are useful for preliminary engineering estimates, but the final schematic must still be checked against real values, tolerances, loads and device operating conditions.

First-order and cascaded RC low-pass and high-pass calculations for quick analog signal-chain checks.
Passive LC sections and third-order ladder filters with source/load impedance taken into account.
Resonant circuits, band-pass and rejection filters for frequency-selective analog tasks.
Operational-amplifier filter topologies with practical component synthesis and response checks.
Small-signal operational-amplifier stages for gain, resistor selection and basic output-range checks.
Calculations for power-supply input filtering, damping, peaking and attenuation estimates.
Thermal-resistance checks for semiconductor junction, package, interface, heatsink and ambient temperature paths.
Auxiliary tools for measurement channels, anti-aliasing filters, ADC acquisition timing and error budgets.
Crystal oscillator helper calculations for selecting load capacitors with stray capacitance taken into account.
Standard-value component utilities for finding practical resistor and capacitor combinations.
