Convert analog signal from 0..3.3 volts to -15..+15 volts

I have an ESP32 with a DAC pin that outputs a variable voltage between 0 and 3.3 V. I need to convert this signal to another voltage range: between -15 and +15 volts. This signal need to drive around 1 A (the more the better). What is the best way…

Interfacing a unipolar 0-5 V output with a bipolar +/- 0.1 V DAQ system using a differential amplifier and voltage divider

I need to connect a sensor system that outputs 0–5 VDC to a data-acquisition system (DAQ) that accepts inputs of ±0.1 VDC (it is designed for a different type of sensor, but I need to repurpose it in this application). (The signals are primarily DC,…

Confused about the sampling rate of AD7606-4 (analog to digital converter)

I'm using an AD7606-4 which is connected to an STM32 EVB. The connection is in the serial configuration and samples only 4 channels (DOUTA only). The sampling rate in the datasheet is 200 ksps, but I can't understand if that is in the parallel or…

Bidirectional Hall current sensor signal conditioning (shift and scale sensor output voltage)

I am using a Hall current sensor in circuitry where I need to implement signal conditioning in order to improve accuracy of measurement. The Hall sensor outputs 1 volt when measuring maximum current in negative direction and 4 V when measuring in…

Send a 60Hz trig signal over a 9m cable

I want to send a trig signal over a 9m cable, the signal is around 60Hz (each 15ms it sends a 1ms pulse). In order to avoid electrical interference I convert the 3.3V original signal with the following circuit: I have a power supply of 24V…

Convert HTL to RS-422

I have to convert a 0-24V (HTL) signal to a RS-422 signal. (It's a signal to enable data acquisition on a device that requires RS-422). We found a device from Motrona (PU210) that converts our HSL encoder signal to RS422 and it works fine. But I…

One Differential end into Single Ended Input

I am trying to test a LvPECL signal into a LVDS receiver (NI 6583). Unfortunately, I currently only have the single-ended segment/connector. Looking at the spec, the single ended receiver should still be able to take one end of the differential…

Minimum voltage reference for ADC

I am looking to measure very low voltage signal (0-0.5V range) and was wondering if it is possible without amplification. I am a bit confused about what the minimum references of ADC can be. Looking at datasheets, for all ADCs I looked at so far,…

Bi-Directional RS-232 / RS-485 translator using MAX3162 IC

I'm trying to communicate with an I2C bus using the Serial Card in my PC (NI PCI485/8). I've created a circuit using the MAX3162 to translate from RS485 to RS232. Then I use the MAX3232 as a level shifter to drop the RS232 to 3.3V. Then it's sent…
