APPLICATION INFORMATION
driving the VREF pin (continued)
Note that the maximum current may be up to 30% higher. The user should ensure that VREF is driven from a
low noise, low drift source, well decoupled to analog ground and capable of driving the maximum I
REF
.

reference decoupling
VREF pin
When the on-chip reference generator is enabled, the VREF pin should be decoupled to the circuit board’s
analog ground plane close to the THS1040 AGND pin via a 1-
μ
F capacitor and a 0.1-
μ
F ceramic capacitor.
REFT and REFB pins
In any mode of operation, the REFT and REFB pins should be decoupled as shown in Figure 37. Use short
board traces between the THS1040 and the capacitors to minimize parasitic inductance.

When using the on-chip BIASREF source, the BIASREF pin should be decoupled to the circuit board’s analog
ground plane close to the THS1040 AGND pin via a 1-

μ
F ceramic capacitor.
