TLV2548-EP: The number of channels of TLV2548-EP

Xiang Maverick

Part Number: TLV2548-EP
Other Parts Discussed in Thread: TLV2548, TLV2544, TLV1544

Is the number of channels of TLV2548-EP 4 or 8?

The datasheet says:

"The 4/8 analog inputs and three internal test inputs are selected by the analog multiplexer depending on the command entered. The input multiplexer is a break-before-make type to reduce input-to-input noise injection
resulting from channel switching"

I aslo observe the orderable parts are TLV2548MPWREP and V62/10603-01XE, what is the difference between them?

Hi Xiang,

The TLV2544 has four channels and the TLV2548 has eight. The datasheet for the TLV2548-EP looks to have been copied over from the commercial version where the TLV1544 and TLV2548 share the same document. There is no physical difference between the two orderable in terms of the datasheet specs, they have different flows from a reliability standpoint though, You can find out more about that here:
