Output Capacitor
The LM4040 does not require an output capacitor across cathode and anode for stability. However, if an output
bypass capacitor is desired, the LM4040 is designed to be stable with all capacitive loads.
SOT-23 Connections
There is a parasitic Schottky diode connected between pins 2 and 3 of the SOT-23 packaged device. Thus, pin 3
of the SOT-23 package must be left floating or connected to pin 2.
Use With ADCs or DACs
The LM4040x-41 is designed to be a cost-effective voltage reference as required in 12-bit data-acquisition
systems. For 12-bit systems operating from 5-V supplies such as the ADS7842 (see
Figure 8
), the LM4040x-41
(4.096 V) permits operation with an LSB of 1 mV.
