Product details
Overview
The MAX1165BCUI+ from Maxim Integrated is a 16-bit, low-power, successive-approximation analog-to-digital converter (ADC) with parallel interface, internal 4.096V reference, ±2.5 LSB INL, and 165ksps sampling rate. It operates from single +4.75V to +5.25V analog and +2.7V to +5.25V digital supplies, consuming 2.7mA with internal reference - ideal for high-accuracy, space-constrained industrial data-acquisition systems.
For engineers reviewing the MAX1165BCUI+ datasheet, MAX1165BCUI+ pinout, MAX1165BCUI+ application, or MAX1165BCUI+ equivalent, this page delivers verified electrical specs, temperature-rated performance (0°C to +70°C), TSSOP-28 package details, and real-world timing behavior - all confirmed from Maxim's official datasheet Rev 2 (8/08).
Technical Context
The MAX1165BCUI+ implements a SAR architecture with integrated track-and-hold, factory-trimmed 4.096V internal reference (±25ppm/°C), and automatic power-down via R/C-controlled standby/shutdown modes. Its 16-bit parallel D0–D15 output supports direct µP bus interfacing without external clocking.
Conversion timing is fully self-contained: 4.7µs max conversion time after second CS fall, 1.1µs acquisition time, and EOC-driven data valid signaling. Input protection includes clamping diodes (AGND −0.3V to AVDD +0.3V), and analog input bandwidth is 4MHz small-signal.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Resolution | 16-bit - delivers 65,536 discrete output codes for high-fidelity signal digitization. |
| INL (Integral Nonlinearity) | ±2.5 LSB - ensures monotonicity and ≤0.038% full-scale error across operating temperature. |
| Sample Rate | 165ksps - supports real-time capture of signals up to 33kHz full-linear bandwidth (SINAD >81dB). |
| Reference Voltage | 4.096V internal - enables precise 1 LSB = 62.5µV scaling without external reference components. |
| Supply Current | 2.7mA at 165ksps with internal reference - balances speed and battery life in portable instrumentation. |
| Operating Temperature | 0°C to +70°C - validated for commercial-grade industrial control and test equipment environments. |
| SINAD | 86–90dB at 1kHz - provides ≥14.3 effective number of bits (ENOB) for demanding measurement accuracy. |
Pinout & Package
MAX1165BCUI+ is housed in a 28-pin Thin Shrink Small Outline Package (TSSOP), 4.4mm × 9.7mm body, 0.65mm pitch, exposed pad optional. Pin 1 marked by dot; pins numbered counterclockwise.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| D0–D15 | Digital output bus (16-bit wide) | Three-state outputs deliver full 16-bit result directly to µP data bus; MSB = D15, LSB = D0. |
| CS | Convert Start control | First falling edge powers up device; second starts conversion; third loads data onto bus when R/C = high. |
| R/C | Read/Convert mode selector | Controls reference buffer power state: low = standby (reference stays on), high = shutdown (reference off after conversion). |
| EOC | End-of-Conversion flag | Active-low signal indicates data validity; falling edge synchronizes µP read timing. |
| AIN | Analog input | Single-ended input referenced to AGND; accepts 0V to VREF range with 40pF input capacitance. |
| REF / REFADJ | Reference I/O | REF outputs 4.096V internal ref (bypass 4.7µF); REFADJ adjusts ref voltage or selects external reference mode (tie to AVDD). |
| AVDD / DVDD | Analog/digital supplies | Separate 4.75–5.25V (AVDD) and 2.7–5.25V (DVDD) rails enable mixed-voltage system integration. |
| AGND / DGND | Analog/digital grounds | Star-ground connection point; requires single-point tie near device to minimize noise coupling. |
Key Features
| Feature | Design Value |
|---|---|
| AutoShutdown™ power management | Reduces supply current to 0.1µA at 10ksps - extends battery life in intermittent-sampling applications. |
| Factory-trimmed internal reference | 4.096V ±0.5% initial accuracy, ±25ppm/°C drift - eliminates external reference IC and calibration overhead. |
| Integrated track-and-hold | 1.1µs acquisition time with <100ps aperture jitter - supports accurate undersampling of >1MHz transients. |
| Parallel 16-bit interface | No external clock required; direct µP bus connection reduces BOM and layout complexity vs. SPI/I²C ADCs. |
| Robust analog input protection | Clamps AIN to AGND −0.3V / AVDD +0.3V - withstands transient overvoltage without external TVS. |
Applications
| Temperature Sensor/Monitor | Industrial Process Control |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit parallel ADC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADS8588SIPM | 8-channel simultaneous-sampling, SPI interface, 1.25MSPS, ±0.5 LSB INL, 3.3V-only supply | Requires external reference and serial interface logic; better for multi-channel sync but higher system complexity | Select for multi-sensor phase-coherent acquisition; avoid if parallel bus and low-power standby are mandatory. |
| AD7606BSTZ | 8-channel, parallel/serial interface, 200ksps, ±0.5 LSB INL, internal 2.5V ref, 5V supply | Lower resolution (16-bit with no missing codes but ±0.5 LSB INL), wider temp range (−40°C to +85°C), larger LQFP-64 package | Choose for extended temperature operation and higher channel count; not drop-in due to pinout and ref voltage mismatch. |
Compared with MAX1165BCUI+, ADS8588SIPM offers higher sample rate and multi-channel capability but sacrifices low-power standby and parallel simplicity; AD7606BSTZ provides superior linearity and ruggedness but demands PCB redesign and lacks AutoShutdown™ current optimization.

FAQ
What is the maximum sampling rate of the MAX1165BCUI+?
The MAX1165BCUI+ achieves a maximum sampling rate of 165ksps, with guaranteed 4.7µs conversion time after the second falling edge of CS. This rate is maintained across its full 0°C to +70°C operating range when powered from +5V supplies and using the internal reference. At lower rates (e.g., 10ksps), AutoShutdown™ reduces total supply current to 0.1µA.
Does the MAX1165BCUI+ require an external reference?
No, the MAX1165BCUI+ does not require an external reference - it integrates a factory-trimmed 4.096V internal reference with ±25ppm/°C temperature coefficient. External reference operation is optional and supported via the REFADJ pin (tie to AVDD to disable internal buffer) or REF pin (drive with external source capable of 100µA DC load and ≤10Ω output impedance).
What is the meaning of the 'B' grade in MAX1165BCUI+?
The 'B' in MAX1165BCUI+ denotes the INL specification grade: ±2.5 LSB over the full −40°C to +85°C range (per datasheet Table "ELECTRICAL CHARACTERISTICS"), and ±2.5 LSB at TA = +85°C. This is tighter than the 'C' grade (±4 LSB) and looser than the 'A' grade (±2 LSB), positioning MAX1165BCUI+ for cost-sensitive commercial applications requiring robust linearity.
How does the R/C pin control power modes in the MAX1165BCUI+?
The R/C pin controls power state during the second falling edge of CS: low = standby mode (reference and buffer remain powered, enabling rapid restart); high = shutdown mode (reference and buffer powered down, reducing current to 0.5µA). In shutdown mode, 10ms wake-up time is required before next conversion to ensure reference settling - critical for maintaining 16-bit accuracy.
Can the MAX1165BCUI+ interface directly with a 3.3V microcontroller?
Yes, the MAX1165BCUI+ supports mixed-supply operation: DVDD accepts +2.7V to +5.25V, so it can be powered from 3.3V while AVDD remains at 5V. Digital outputs (D0–D15, EOC) meet 3.3V logic thresholds (VIH = 0.7×DVDD = 2.31V min, VOL = 0.4V max at 1.6mA sink), enabling direct connection to 3.3V µP buses without level shifters.
