The pipelined architecture keeps latency low while maintaining 8-bit resolution across the full Nyquist band. Two internal S/H circuits feed dedicated converters — no mux switching, so the phase relationship between channel A and channel B is preserved sample-to-sample. That makes this part a natural fit for I/Q demodulation in software-defined radio, dual-axis position feedback in servo drives, or simultaneous current/voltage sensing in power monitoring. ## Input flexibility and reference options Each channel accepts either differential or single-ended inputs, configurable per channel. The reference can be driven externally or sourced from the internal bandgap. ## Industrial temperature grade and package Rated for -40°C to 85°C, this ADC is suited for environments where the board sees seasonal temperature swings or self-heating from adjacent power stages. ## Lifecycle and sourcing No last-time-buy notice is in effect, and the part carries ROHS3 compliance.","metaTitle":"MAX1191ETI+ 8-Bit 7.5Msps Dual ADC, Simultaneous Sampling","metaDescription":"MAX1191ETI+ 8-bit pipelined ADC, dual-channel simultaneous sampling at 7.5 Msps.

The MAX1191ETI+ has two internal sample-and-hold circuits feeding two dedicated 8-bit pipelined ADCs, with a 1:1 S/H-to-ADC ratio per channel. Both channels sample simultaneously at 7.5 Msps, preserving the phase relationship between inputs."},{"question":"What is the maximum sampling rate of MAX1191ETI+?","answer":"The maximum sampling rate is 7.5 Msps per second per channel. Both channels run at this rate simultaneously."},{"question":"What are the equivalents for MAX1191ETI+?","answer":"Within the same Maxim family, the MAX1191 is the base dual 8-bit 7.5 Msps part. No pin-compatible second source from another manufacturer is listed in the official cross-reference. For a dual-sourcing strategy, evaluate the pinout and timing against the MAX1192 (10-bit version) if resolution headroom is acceptable — but verify the pin compatibility against the respective datasheets before committing the board layout."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/analog-devices/MAX1191ETI","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/analog-devices/MAX1191ETI when reusing this data.
