In pseudo-differential mode, the 4 inputs are each paired with a dedicated return line. The reference can be internal or external. ## Package and mounting — 16-QSOP for tight boards The MAX11603EEE+ comes in a 16-lead QSOP (3.90 mm body width), a surface-mount package that fits on dense mixed-signal boards alongside a small MCU and a few passives. The tube shipment is fine for bench builds; for production reels, check the 'T' suffix variant. The 0.154-inch (3.90 mm) width keeps the footprint compact — useful when the ADC shares a board edge with a connector bank. ## Lifecycle and sourcing reality The MAX11603EEE+ carries an active lifecycle status from Maxim (now part of Analog Devices). For a BOM line that needs an 8-bit I²C ADC, this is a safe choice for new designs — no imminent obsolescence risk.","metaTitle":"MAX11603EEE+ 8-Bit SAR ADC, 188k SPS, I²C, 16-QSOP","metaDescription":"Maxim MAX11603EEE+ 8-bit SAR ADC, 188k samples/sec, I²C interface, 4/8 input channels, -40°C to 85°C, 16-QSOP.

The data interface is I²C. The ADC is a bus slave; the microcontroller writes configuration bytes and reads conversion results over the same two-wire bus."},{"question":"What is the resolution of MAX11603EEE+?","answer":"8 bits. Each conversion produces an 8-bit digital output, giving 256 discrete levels across the analog input range."},{"question":"Is MAX11603EEE+ compatible with 3.3V logic?","answer":"Yes. The digital supply range is 2.7V to 3.6V, which covers 3.3V logic levels directly. The I²C bus also operates at 3.3V without level shifting."},{"question":"What is the closest pin-compatible alternative to MAX11603EEE+ in this component family?","answer":"Within the same Maxim MAX1160x family, the 10-bit MAX11605EEE+ and 12-bit MAX11606EEE+ share the same 16-QSOP package and pinout, offering higher resolution at the same 188k SPS and I²C interface. If 8 bits are sufficient, the MAX11603EEE+ is the correct fit; stepping to 10 or 12 bits costs a few extra LSBs of noise but keeps the same board layout."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/analog-devices/MAX11603EEE","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/analog-devices/MAX11603EEE when reusing this data.
