Other Parts Discussed in Thread: DRV134 , DRV135 , INA163 , INA134 Hi team
My customer met a problem regarding audio output noise:
The 3.5mm analog audio output of the device was found to be noisy and current noise was suspected, after adding an…
Part Number: DRV135 Other Parts Discussed in Thread: INA134 , I have a customer that uses standard connectors for both TX (DRV135) and RX (INA134) paths in their application.
As a result, it's fairly easy to mistakenly swap connections.
When this…
Hi Todd,
Thank you for your post. This design should be okay.
However, you may want to consider using the INA1651 instead of the INA134/137 for your receiver. The INA1651 has higher input impedance so in the event that you want to drive more than…
Heiko,
Regarding the offset drift: I will mention your comment to the development team (i.e. that it would be good to specify drift over 0C to 85C). Over the full range the two products are somewhat comparable(0.6uV/C vs 0.8uV/C).
I will loop the…
Part Number: DRV135 Other Parts Discussed in Thread: INA134 , , INA137 Hi,
In my application a differential MEMS microphone signal is to be driven over max. 300m where a differential ADC is used to sample it. DRV135 is a single to differential line…
Lucas,
The input resistance is listed for many amplifiers. You can find it in the same section as the input capacitance (see example below for OPA206). If the data sheet does not list the input impedance Marek provides a procedure for finding this value…
Part Number: TLV320DAC32 Other Parts Discussed in Thread: TLV320ADC3101 , , DRV134 , INA134 Dear Support team,
May I ask about the recommended line driver for TLV320DAC32 and line receiver for TLV320ADC3101?
Does DRV134/5 match with DAC32?
Does…
The three resistors shown in the schematic are just for the test circuit.
R1 and R2 are driver-side pull-downs (high-ish resistance, probably 100k or so). RL is for the test circuit -- it sets the load resistance to 600 ohms because that is how the…
Part Number: DRV134 Other Parts Discussed in Thread: INA134 , PGA2311 Hello,
I'm designing a preamp around the PGA2311 and I'm using the DRV134 and INA134 chips to facilitate balanced I/O. I want to maintain the largest signal swing I can within the…
Hello,
The comparison is tricky because the INA134 is a difference amplifier and the INA128 is an instrumentation amplifier.
While both can technically be used as an audio differential line receiver, the INA134 has much lower distortion and noise…
