TLP7830
1. Applications
• Motor phase and rail current sensing
• Power inverter current and voltage sensing
2. General
The TLP7830 is a 1-bit, second-order sigma-delta (∑-∆) modulator converts an analog input signal into a high-
speed data stream with galvanic isolation based on optical coupling technology.
3. Features
(1) Output clock frequency: 10 MHz (typ.)
(2) 16 bits resolution no missing codes [ENOB:12 bits(typ.)]
(3) Integral non-linearity: 4 LSB (typ.)
(4) Input offset voltage: 0.6 mV (typ.)
(5) Operating temperature range: -40 to 105 
(6) Common-mode transient immunity: 15 kV/µs (min)
