The input multiplexer can be configured for six differential or twelve single-ended channels, with the S/H-ADC ratio fixed at 1:1. ## Package and board-fit for the 16-pin SSOP/QSOP footprint Surface-mount assembly with tube shipment; the narrow-body SSOP/QSOP footprint suits dense mixed-signal boards where board real estate is at a premium. ## Reference options and conversion architecture The reference can be driven from an external source or the internal bandgap, giving the designer control over the full-scale range independent of the supply voltage. A single ADC core handles all channels with a 1:1 sample-and-hold to converter ratio, meaning each conversion samples the input at that instant — no pipeline delay between channels. Sourced to order through independent distribution; availability and current pricing confirmed at RFQ.","metaTitle":"MAX1239KEEE+ Analog Devices SAR ADC, 12-Bit, 94.4kSPS","metaDescription":"MAX1239KEEE+ 12-bit SAR ADC, 94.4kSPS, I²C interface, 6/12 inputs, -40 to +85°C.
