Page

• Added SOT-23-14 (DYY) package in Device Information ..................................................................................1

• Removed WQFN (RTE) package from Device Information ............................................................................... 1

• Removed SOT-553 (DRL) package from Description ........................................................................................1

• Added SOT-23-14 (DYY) package in Pin Configuration and Functions section ................................................ 4

• Removed WQFN (RTE) package in Pin Configuration and Functions section ..................................................4

• Corrected two typos mislabeling the RUC package as a "WQFN" package instead of as a "X2QFN" package

in Pin Configuration and Functions section ....................................................................................................... 4

• Corrected typo mislabeling the RUC package as having an "Exposed Thermal Pad" in Pin Configuration and

Functions section ...............................................................................................................................................4

• Added X2QFN pinout to Pin Functions: OPA4991 in Pin Configuration and Functions section ........................ 4

• Updated OPA991S DBV and DRL pinout to correct typo mislabeling "SHDN" pin as the "NC" pin in Pin

Configuration and Functions section ................................................................................................................. 4

• Removed overbar on "SHDN" pin from OPA2991S DGS and RUG pinouts for added clarity and consistency

in the Pin Configuration and Functions section ................................................................................................. 4

• Added SOT-23-14 (DYY) package in Thermal Information for Quad Channel section.....................................10

• Removed "OPA4991S" from header of Thermal Information for Quad Channel section..................................10

• Corrected typo mislabeling the RUC package as a "WQFN" package instead of as a "X2QFN" package in

Thermal Information for Quad Channel section................................................................................................10

• Removed the overbar from the SHDN pin name in the note on toff and ton in the Electrical

Characteristics section for consistency.............................................................................................................11

• Changed input resistor values in Equivalent Internal ESD Circuitry Relative to a Typical Circuit Application in

Electrical Overstress section to more closely resemble device ....................................................................... 27

• Removed WQFN (RTE) package from Packages With an Exposed Thermal Pad ..........................................30

• Expanded the Shutdown section in the Detailed Description section to further clarify shutdown operation. Also

corrected the current consumption in shutdown from 20µA to 30µA, the valid logic low voltage threshold from

"V- + 0.4 V" to "V- + 0.2 V", the valid logic high voltage threshold from "V- + 1.2 V" to "V- + 1.1 V", and the

"typical enable time" in the section from 30µs to 8µs to align with the Electrical Characteristics section ........30
