INL (Integral Non-Linearity):
Public: ±0.0015% FS
Exclusive: ±0.0022% FS at 125°C after 1000 hours → Design for 0.003% to be safe.

Public Pinout: 8-pin SOIC, pins 1=OUT, 2=V-, 3=IN+, 4=V+, 5=NC, 6=IN-, 7=VSET, 8=GND. (Incorrect – this swaps the power pins.)

Part 8: Firmware – Exclusive Code Snippets

Here is the official but unpublished initialization sequence recommended by the 9892 application team:

Thermal pad connection: The exposed pad must be connected to V-, not GND. Public sheets often say "connect to ground plane" – that is a mistake leading to 15°C higher junction temperature.
Feedback trace length: Keep under 8mm. The exclusive version explains why: the 9892’s error amplifier has a gain-bandwidth of 12 MHz, and traces longer than 8mm become antennas for switching noise.
Decoupling capacitors: Two capacitors (0.1µF X7R + 4.7µF tantalum) are mandatory. The exclusive sheet specifies the exact placement relative to pin 4 and pin 8, with a measured loop inductance < 5nH.
