JAJSQ78A april 2023 – august 2023 LMH32401-Q1
PRODUCTION DATA
The LMH32401-Q1 operates on 3.3-V supplies. Always drive the VDD1 and VDD2 pins from the same supply source, and individually bypass these two pins. Always maintain a low power-supply source impedance across frequency; therefore, use multiple bypass capacitors in parallel. Place the bypass capacitors as close as possible to the supply pins. Place the smallest capacitor on the same side of the PCB as the LMH32401-Q1 device. If possible, place the larger-valued bypass capacitors on the same side of the PCB. However, if space constraints are an issue, then move the capacitors to the opposite side of the PCB using multiple vias to reduce the series inductance resulting from the vias. To operate the LMH32401-Q1 on bipolar supplies, connect pins 1 and 7 to the negative supply. Always connect the thermal pad to the most negative supply. Appropriately level shift the digital pin threshold voltages because the pins are connected to voltages at pins 1 and 7.
