FAQ

What is the primary purpose of the MAX11160EVKIT#?

The MAX11160EVKIT# is a fully assembled evaluation kit designed exclusively to validate and prototype with the MAX11160 16-bit, 500ksps SAR ADC. It provides calibrated analog signal paths, optimized power delivery, SPI-compatible interface options, and direct access to all critical pins - enabling engineers to verify DC accuracy, AC performance (91.7dB SNR, -103dB THD), and timing behavior of the MAX11160 under real-world conditions before committing to custom PCB design.

Does the MAX11160EVKIT# support daisy-chaining multiple MAX11160 devices?

Yes, the MAX11160EVKIT# supports daisy-chain configuration for multi-ADC systems. Its onboard jumpers and header routing allow SDO-to-SDI cascading between MAX11160 units, with shared CNVST and SCLK signals. The kit validates the MAX11160's built-in busy-indicator feature in daisy-chain mode - eliminating external timing circuits by signaling conversion completion via SDO prior to data readback.

Can the MAX11160EVKIT# be used to evaluate the internal reference performance of the MAX11160?

Yes, the MAX11160EVKIT# provides direct test points and a dedicated 10µF X5R/X7R capacitor at the REF pin to characterize the MAX11160's internal 4.096V reference. Users can measure initial accuracy (4.092–4.100V), temperature coefficient (±7ppm/°C), output impedance (0.1Ω), and long-term drift - confirming its suitability for precision unipolar 0–5V measurements without external reference components.

What op-amp is used on the MAX11160EVKIT# for analog input buffering?

The MAX11160EVKIT# uses the MAX9632 op-amp as the recommended input buffer for the MAX11160. This low-noise (0.9nV/√Hz), high-bandwidth (55MHz) amplifier ensures 16-bit settling within the 0.5µs acquisition window, preserves 91.7dB SNR, and maintains -128dB THD at 10kHz - directly supporting the MAX11160's specified dynamic performance when driving high-impedance sources or multiplexed sensor arrays.

Is the MAX11160EVKIT# compatible with 3.3V logic systems?

Yes, the MAX11160EVKIT# supports 3.3V digital logic through configurable OVDD supply routing. The kit allows OVDD to be set between 2.3V and 5.25V, and includes level-shifting compatibility for SPI/QSPI/MICROWIRE interfaces operating at 3.3V. All digital timing parameters - including tSCLK (20ns min), tDSDO (18ns), and setup/hold windows - are validated for reliable communication with 3.3V host controllers when using the MAX11160EVKIT#.
