Part Number: DAC53401EVM Other Parts Discussed in Thread: BOOSTXL-DAC-PORT , , TPL1401EVM , MSP432E401Y Hi team,
If the MSP432E401Y+BOOSTXL-DAC-PORT+TPL1401EVM are evaluated correctly, does the firmware have to be upgraded when they put DAC53401EVM…
I tried to capture SCL&SDA signal on TPL1401EVM, and I could capture I2C signal by modifying VREF or BASE OUTPUT, but EEPROM and RELOAD could not capture signal。
Below is an example circuit to program a LASER diode APC circuit. The TPL1401 provides an 8-bit, programmable DC bias and integrates a precision internal reference. The high-speed modulation DAC used for the modulation input will not need to drive the…
By default, the TPL1401 will power down to high impedance. This is important for applications like power supply margining and scaling where you don’t want the device to drive the output low when it’s powered down. When taken out of power down, the device…
Yes. By default, the TPL1401 uses the VDD supply voltage as the reference and you can supply an external reference to that pin. If using the supply as the reference, this means that the reference needs to fall in the 1.8V to 5.5V supply range of the TPL1401…
There is a 30ms power-on reset (POR) delay. The POR causes all registers to initialize to default values, and communication with the device is valid only after the 30ms POR delay. The default values or user modified values for all the registers in the…
The exposed feedback pin, FB, is the feedback path for the internal output buffer.
The exposed feedback pin is beneficial in some applications.
In the circuit below, the TPL1401 used as a programmable comparator. The comparator threshold is set…
The update rate of the TPL1401 will depend on how fast data can be written to the device. The TPL1401 supports I 2 C standard mode (100 kbps), fast mode (400 kbps), and fast mode plus (1 Mbps). This TIPL training goes through how to calculate the update…
It is possible to use the TPL1401 as an 8bit programmable comparator. To do this, write the desired comparator threshold value to the DPOT_POS bits in the DPOT_POSITION register. Find the correct code using the transfer function below:
(Register…
Yes, it is possible to supply the TPL1401 with a Zener diode. The voltage of the Zener would need to be in the 1.8V to 5.5V supply range of the TPL1401.
When designing the power supply circuit, pay close attention to the specifications of the Zener…
