Hi Danilo,
TIPD175 provides a pretty in depth error analysis of the circuit in Appendix B of the document. Can the customer use this as a starting point? The typical error sources in a design are due to the offset voltage, input bias current, CMRR, and…
Other Parts Discussed in Thread: TPS2546 , TIPD104 , TIPD129 , TIPD156 , TIPD175 Hi Team,
my customer would like to use TPS2546 switch for the USB port charging. (5V/3A)
If the system need to detect the charging current and the SOC has the ADC, did we have…
Other Parts Discussed in Thread: OPA211 , TIPD175 , THS4521 Hi,
I am looking for some product that can help me do the following. I have 10MHz differential signals with voltage range from 100uV to 2mV. I want to amplify them with good CMRR differential amplifier…
Hello Francois,
The op amp you are looking for is the OPA2333 —which is the OPA333 op amp in a dual package. This rail to rail op amp with low offset voltage, low supply voltage, and the BW you require will work perfectly.
We have a TI Precision…
Hello Degu,
This is similar to a TI Precision Design that we have. You may find some if it helpful. Here is the link: http://www.ti.com/tool/tipd175
Note that the layout is important...make the input traces as short and balanced as possible. Be sure to…
Hello Mohammad,
Given such large voltages, a discrete difference amplifier is likely your best option. Such a circuit looks like your first figure but without the level shifter since VREF can be added using the differential amplifier. With respect…
Hello Paolo,
Detecting such a wide range of current is definitely challenging, especially given 1MHz BW. The options we typically see are either changing the gain of the device (e.g. using a PGA as in TIPD135) or switching in different sense resistors…
