Checkfor Samples: LMC6442
1FEATURES DESCRIPTIONThe LMC6442is ideal for battery powered systems,
(Typical,VS= 2.2V) where very low supply current (less than one
• Output Swingto Within30 mVof Supply Rail microamp per amplifier) and Rail-to-Rail output swing
High Voltage Gain 103 dB is required.It is characterized for 2.2V to 10V
operation, andat 2.2V supply, the LMC6442is ideal
• Gain Bandwidth Product 9.5 KHz for single (Li-Ion) or two cell (NiCad or alkaline)
• Ensured for: 2.2V, 5V, 10V battery systems.
• Low Supply Current 0.95µ A/Amplifier The LMC6442 is designed for battery powered
• Input Voltage Range −0.3VtoV+ -0.9V systems that require long service life through low
2.1µ W/Amplifier Power Consumption supply current, such as smoke and gas detectors,
and pageror personal communications systems.
• Stable for AV≥+2or AV≤−1Operation from single supplyis enhancedby the wide
APPLICATIONS common mode input voltage range which includes the
ground (or negative supply) for ground sensing
• Portable Instruments applications. Very low(5 fA, typical) input bias current
• Smoke/Gas/CO/Fire Detectors and near constant supply current over supply voltage
Pagers/Cell Phones enhance the LMC6442's performance near the end-
of-life battery voltage.
• Instrumentation Thermostats Designed for closed loop gainsof greater than plus
two (or minus one), the amplifier has typically 9.5
• Occupancy Sensors KHz GBWP (Gain Bandwidth Product). Unity gain can
• Cameras be used witha simple compensation circuit, which
Active Badges also allows capacitive loadsof upto 300 pFto be
driven, as describedin the Application Information
section.
