Dual ATE driver/comparator in 100-TQFP-EP
The MAX9969ALCCQ is a dual-function device combining a comparator and driver for automated test equipment (ATE) pin electronics — a 2-bit logic type that handles both drive and compare on the same pin channel. It requires split supply rails: a negative rail of -4.5V to -5.25V and a positive rail of 9.5V to 10.5V. This dual-supply architecture is typical for ATE pin drivers that need to swing below ground for level-shifting.
The -4.5V to -5.25V negative rail is unusual — most mixed-signal ATE parts use a single -5.2V supply, but this part's range allows some tolerance for regulator variation. The positive rail at 9.5V to 10.5V is similarly tight, meaning the power design must use precision regulators, not generic 10V rails. If your test head sees thermal cycling beyond 70°C, this grade will not hold.
RoHS non-compliant — the part contains lead in the solder finish. If your assembly line is RoHS-exempt (e.g., ATE spare parts, military, or medical), this is acceptable; otherwise, confirm the exemption or plan for a lead-free alternative.
