Technical Details & Description

Dual 8-bit ADC with simultaneous capture at 7.5 Msps

The Maxim Integrated MAX1191ETI+ is a dual 8-bit pipelined ADC that samples two channels simultaneously at 7.5 Msps each. 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.

No last-time-buy notice is in effect, and the part carries ROHS3 compliance.

Frequently asked questions

Does MAX1191ETI+ support simultaneous sampling of two channels?

Yes. 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.

What is the maximum sampling rate of MAX1191ETI+?

The maximum sampling rate is 7.5 Msps per second per channel. Both channels run at this rate simultaneously.

What are the equivalents for MAX1191ETI+?

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.
