Part Number: TPA2025D1 We have a TPA2025D1 in a design driving a 8 Ohm speaker at around 1.5W. I need to modify the design so that the PA output has an electronic switch to switch between two speakers
1. the original 8 Ohm speaker at 1.5W
2. a smaller…
Hi Switch,
It's been some long time since last communication, but I've got some test results from EVM:
I measure ~5mA quiescent current when powering the EVM from 3.6V. This is with the inductor in place.
However boost is not enabled (PVDD ~…
Part Number: TPA2025D1 I downloaded the TPA2025D1 macro from the TI website and created the following circuit, I basically wanted to simulate the circuit of the evaluation board. I have a few questions:
I want to simulate using different inductance values…
Part Number: TPA2025D1 Hi Team,
One of my customer is using TPA2025D1, they reported, if they weak pull up the ENABLE pin, saying ~10Mohms, there are some middle voltage was observed on the pin. As previous feedback from BU, there is no internal pull-up…
Part Number: TPA2025D1 Hi All,
Is there any instruction of PVDD ripple of TPA2025D1.
Is it ok PVDD ripple is around 1V when input =3.5V/4.35V?
3.5V input， PVDD ripple
4.35V input ， PVDD ripple
Part Number: TPA2025D1 Hello
I have designed and built prototype amplifier circuits using the TPA2025D1 chip and the design largely mirrors the schematic found in the TPA2025D1EVM datasheet. I am using the circuits to drive 8 ohm voice coil shakers.

Part Number: TPA2025D1 Other Parts Discussed in Thread: TINA-TI Hello
I want to build a low power amplifier with cutoff frequencies at 10Hz and 10kHz (weird freqs, I know, but it's supposed to be like that). I'm using this Spice model of the TPA2025D1…
Part Number: TPA2025D1 Other Parts Discussed in Thread: TPA2015D1 I understand that TPA2025 has a fixed gain of 20dB.
Can we use external circuit to reduce the gain? (For example using resistors?)
Objective is to maximise the dynamic range of MCU DAC…
