Frequently asked questions

Where can I buy ADA4891-4WARUZ-R7 in tape and reel packaging?

This part is supplied in Tape & Reel (TR) or Cut Tape (CT). It is sourced to order through independent distribution; submit an RFQ for current availability and pricing.

Is ADA4891-4WARUZ-R7 a direct replacement for ADA4891-4?

The -R7 suffix denotes Tape & Reel packaging; the base ADA4891-4 die and electrical specs are identical. The part is functionally the same.

What are the best cross-reference or alternate parts for ADA4891-4WARUZ-R7?

For a two-channel alternative, the ADA4891-2ARZ-RL shares the same 105 MHz GBP and 2 pA bias in an 8-pin package. The AD8054ARUZ-REEL7 is a quad voltage-feedback op-amp with 160 MHz bandwidth and 190 V/µs slew rate in the same 14-TSSOP footprint.
