MAX44205 Evaluation Kit
Evaluates: MAX44205
General Description
The MAX44205 evaluation kit (EV kit) provides a
proven design to evaluate the MAX44205, low-noise, low-
distortion fully differential operational amplifier (op amp),
suitable for driving high-resolution SAR ADCs such as the
MAX11905 family of devices.
The EV kit PCB comes installed with a MAX44205ATC+
in a 12-pin, 3mm x 3mm TQFN package with an exposed
pad.
Benefits and Features
●● Fully Differential Amplifier with 130dBc THD
●● +2.7V to +13.2V Supply Voltage Range
●● Output-Voltage Clamps to Prevent Overranging ADC
●● Adjustable Output Common-Mode Voltage
●● Evaluate 20-Bit SAR ADC + MAX44205 Amplifier
(refer to the MAX11905 EV Kit)
●● Proven PCB Layout
●● Fully Assembled and Tested
Ordering Information appears at end of data sheet.
Quick Start
Required Equipment
●● MAX44205 EV kit
●● ±5V, 100mA dual DC power supply
●● Low-distortion differential-output signal genera-
tor (i.e., Audio Precision 2700, Stanford Research
DS360)
●● 2-channel oscilloscope
●● Two SMA cables of equal length
Procedure
The EV kit is fully assembled and tested. Follow the
steps below to verify the board operation:
1) Verify that all shunts are in their default positions, as
shown in Table 1.
2) Connect the ±5V supply to the VS+, VS-, and GND
test points, respectively.
3) Use the SMA cables and connect the 10kHz,
6.6Vp-p sine, differential input from the signal
generator to the INP and INM SMAs on the EV kit.
4) Turn on the power supplies.
5) Use the oscilloscope and monitor the differential
output at jumper JU6.
