illustrate
Using a new patent-pending circuit topology, the LM6142/LM6144 provides a new level of performance that requires compromises before applying low-voltage supplies or power limits. Operating from over 24V, 1.8V mains, the LM6142/LM6144 are an excellent choice for battery-powered systems, portable instruments, and others.
Greater than the rail-to-rail input voltage range eliminates concerns about exceeding the common mode voltage range. Rail-to-rail output swing output provides maximum dynamic range. This is especially important when operating at low supply voltages.
The high gain bandwidth and 650μA/amplifier supply current open up new battery-powered applications where previously higher power consumption reduces battery life to unacceptable levels. The ability to drive large capacitive loads without oscillation removes this common problem.
