Photocouplers Optically Isolated Delta-Sigma Modulator
TLP7930,TLP7930F
TLP7930,TLP7930F
1. Applications
• Motor phase and rail current sensing • Power inverter current and voltage sensing
2. General
The TLP7930 and TLP7930F are 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: 1.4 mV (typ.) (5) Operating temperature range: -40 to 105 (6) Common-mode transient immunity: 15 kV/µs (min) (7) Safety standards
