AC-Coupled Corner Frequency
Capacitors C7, C9, C10, and C14 provide the option to ac couple the input of the INA1650 and capacitors
C8 and C12 provide the option to ac couple the output of the INA1650. Equation 1 and Equation 2
calculate the high pass corner frequency of input A and input B due to capacitors, C7, C9, C10, and C14
on the input.

Start-Up Time
Capacitor C11 increases the settling time of the VMID (OUT) pin due to the resistance of the internal
voltage divider for VMID (IN) and C11 creating an RC time constant. Equation 8 calculates one RC time
constant.
tRC = 250 kW ´ C11

Figure 3 displays the rate at which an RC circuit charges to its final value. Notice at one time constant, the
voltage across the capacitor is at 63.2% of its final value.

To decrease the settling time of the VMID (OUT) voltage the Zener diode, D1, can be populated. The
Zener voltage of the diode should be chosen to be greater than 100 mV more than one half of the supply
voltage. Equation 9 calculates the recommended Zener voltage of the diode (Vz). Note that due to the
leakage current of the Zener diode interacting with the internal voltage divider resistance an error may be
seen on the VMID (OUT) pin.

Increasing the Common-Mode Input Impedance
The high CMRR of many line receivers can be degraded by source impedance mismatches in the system.
Resistors R4 and R6 provide an option to increase the common-mode input impedance of the INA1650 to
reduce the effects of source impedance mismatch. For an explanation on the effects of increasing the
common-mode input impedance please refer to section 8.1.2 of the INA1650 product data sheet
(SBOS818).

Single-Ended Input to Differential Output
Jumper J11 allows the INA1650EVM to convert single-ended signals to differential signals. To set up the
EVM to create a differential output from a single-ended input, first place a shunt across J11, then remove
resistors R3 and R9, and finally, install resistor R11 and capacitor C16 if required in the design. To apply a
single-ended signal, insert a jumper wire from –IN A to GND and +IN B to GND into terminal blocks J3
and J4, respectively, and insert a wire into +IN A of terminal block J3 and tighten down the screws of the
terminal blocks. The single-ended input can then be applied through the wire connected to +IN A. Figure 4
shows how the connections should be made for a single-ended input to differential output.

Common-Mode Rejection Ratio
The common-mode rejection ratio measurement was performed by applying a 1-Vrms common-mode
signal to the input and measuring the gain of the signal at the output. The frequency of the input signal
was swept from 20 Hz to 90 kHz and the measurement bandwidth of the Audio Precision APx555 was set
to 90 kHz. Differences in common-mode rejection between the left and right channel can occur and may
vary from part to part. Figure 7 shows a measurement of the common-mode rejection ratio.

Board Layout
This section provides a description of the INA1650EVM board layout and layer illustrations.
5.1
Layout
The board layout for the INA1650EVM is shown in Figure 13 and Figure 14. The top layer consists of all
signal traces and is poured with a solid ground plane. The traces of the positive input (IN+ A, IN+ B) and
negative input (IN- A, IN- B) were kept as balanced as possible to reduce the possibility of a differential
voltage from developing due to trace impedance mismatch. The decoupling capacitors, C3, C6, C15, and
C13, were positioned as close as possible to the power supply pins of the device. Minimal traces were
routed on the bottom layer so that a large solid ground plane could be poured. Vias were placed at the
ground connection of every component to provide a low-impedance path on the bottom layer back to the
supply ground. The traces from J15 to VREF A and VREF B were kept as short as possible to maintain
the exceptional common-mode rejection of the INA1650.
