Active production — current BOM fit
The MAX6225ACSA+: ROHS3 compliant per the manufacturer, so it slots into lead-free assembly flows without a waiver.
2.5 V reference — noise and drift that matter for precision
Fixed 2.5 V output with ±0.04 % initial tolerance — that is ±1 mV at 25 °C, tight enough to set the full-scale of a 16-bit ADC without external trimming.
Supply headroom and load drive
Output current is rated 15 mA, enough to bias the reference input of multiple ADCs or a small sensor bridge, while the supply current draw is only 3 mA.
Package and board integration
Housed in an 8-pin SOIC (0.154-inch body width, 3.90 mm), surface-mount — the standard footprint for a precision analog subcircuit on a mixed-signal board. Supplied in tube packaging, so it arrives in an ESD-safe carrier suitable for manual pick-and-place or small-batch assembly without reel fees.
