If you need datasheets of this product, please contact us.
- Low Operating Voltage (1.8V to 5.5V)
- Low Operating Current (
PS=off (Vps=1 to 2V) 600µA typ. @ V+=2V, no input signal
PS=on (Vps= -0.3V to +0.6V ) 13µA typ. @ V+=2V, no input signal)
note: During power saving mode ON, operation of wave forming stops.
- Input bias current (50nA typ.)
- Excellent response time (
1.2µsec typ. @ input signal level: 1050mV → 950mV
1.2µsec typ. @ input signal level: 950mV → 1050mV)
- Rail-to-Rail Output
note: Output is in the opposite in polarity (inverted )from input.
- Bipolar Technology
- Package Outline (MSOP10 (TVSP10) MEET JEDEC MO-187-DA / THIN TYPE 2.9mm x 4mm)
The NJM2299 is a low - current wave shaping circuit to change a noisy or weak demodulated FSK signal to the original digital signal. Low bit-rate demodulated signal is especially suitable for input signal. Our unique circuit features excellent response characteristics for intermittent operation. It may be also helpful to prevent the read-error of the data including continuous '00' or 'FF' data.
