MAX410/MAX412/MAX414
TDFN Exposed Paddle Connection
On TDFN packages, there is an exposed paddle that
does not carry any current but should be connected to
V- (not the GND plane) for rated power dissipation.
Total Supply Voltage Considerations
Although the MAX410/MAX412/MAX414 are specified
with ±5V power supplies, they are also capable of sin-
gle-supply operation with voltages as low as 4.8V. The
minimum input voltage range for normal amplifier oper-
ation is between V- + 1.5V and V+ - 1.5V. The minimum
room-temperature output voltage range (with 2kΩ load)
is between V+ - 1.4V and V- + 1.3V for total supply volt-
ages between 4.8V and 10V. The output voltage range,
referenced to the supply voltages, decreases slightly
over temperature, as indicated in the ±5V
Electrical
Characteristics tables. Operating characteristics at total
supply, voltages of less than 10V are guaranteed by
design and PSRR tests.
MAX410 Offset Voltage Null
The offset null circuit of Figure 9 provides approximately
±450µV of offset adjustment range, sufficient for zeroing
offset over the full operating temperature range.
