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 |
