| 不知道LM393和LM2904算不算“轨到轨”的,如果能用的话,团不团就无所谓了,东明都有。 LM393参数:
 ■ Wide single-supply voltage range or dual
 supplies: +2V to +36V or ±1V to ±18V
 ■ Very low supply current (0.4mA) independent
 of supply voltage (1mW/comparator at +5V)
 ■ Low input bias current: 25nA typ.
 ■ Low input offset current: ±5nA typ.
 ■ Low input offset voltage: ±1mV typ.
 ■ Input common-mode voltage range includes
 ground
 ■ Low output saturation voltage: 250mV typ. (Io =
 4mA)
 ■ Differential input voltage range equal to the
 supply voltage
 ■ TTL, DTL, ECL, MOS, CMOS compatible
 outputs
 
 LM393参数:
 ■ Internally frequency compensated
 ■ Large DC voltage gain: 100 dB
 ■ Wide bandwidth (unity gain: 1.1 MHz
 temperature compensated)
 ■ Very low supply current per operator (500 μA)
 ■ Low input bias current: 20 nA
 (temperaturecompensated)
 ■ Low input offset current: 2 nA
 ■ Input common-mode voltage range includes
 ground
 ■ Differential input voltage range equal to the
 power supply voltage
 ■ Large output voltage swing 0 V to VCC - 1.5 V
 ■ Internal ESD protection:
 – 2kV HBM
 – 200 V MM
