Product details
Overview
The MAX1162CCUB+ from Maxim Integrated is a 16-bit successive-approximation analog-to-digital converter (ADC) with SPI/QSPI/MICROWIRE-compatible serial interface, +5V single-supply operation, and 200ksps maximum sampling rate. It features internal track-and-hold, 4MHz input bandwidth, ±4 LSB integral nonlinearity at 0°C to +70°C, and 10µA shutdown current - enabling high-precision data acquisition in space-constrained, battery-powered systems such as portable instrumentation and industrial I/O modules.
For engineers reviewing the MAX1162CCUB+ datasheet, MAX1162CCUB+ pinout, MAX1162CCUB+ application, or MAX1162CCUB+ equivalent, this page delivers verified technical context, real-world design meaning of key specs, validated µMAX package pin functions, and two confirmed alternative parts for thermal, accuracy, and power trade-offs in embedded sensor interfaces.
Technical Context
The MAX1162CCUB+ implements a SAR architecture with integrated track-and-hold, supporting unipolar conversion over 0V to VREF with 16-bit no-missing-codes resolution. Its serial interface operates at up to 4.8MHz SCLK with CPOL=0/CPHA=0 timing, requiring 24 clock cycles per conversion (eight leading zeros + 16 data bits MSB-first).
Power management uses AutoShutdown™: CS high forces shutdown (≤10µA), while CS low initiates acquisition and conversion. Acquisition time is fixed at 1.1µs, independent of source impedance below 1kΩ, and full-scale range is set by external reference voltage (3.8V to AVDD).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Resolution | 16-bit, no missing codes - guarantees monotonicity and full code coverage for precision measurement applications. |
| Sampling Rate | 200ksps max - supports real-time capture of signals up to 10kHz full-linear bandwidth (SINAD > 86dB). |
| INL | ±4 LSB (0°C to +70°C) - defines end-point linearity error affecting absolute accuracy in calibrated systems. |
| Supply Current | 2.75mA at 200ksps (AVDD = DVDD = +5V) - enables low-power operation without sacrificing throughput. |
| Shutdown Current | ≤10µA - allows rapid power gating between conversions to extend battery life in portable equipment. |
| Input Bandwidth | 4MHz - permits accurate digitization of fast transients and supports undersampling of higher-frequency periodic signals. |
| SPI Compatibility | CPOL=0, CPHA=0, 4.8MHz max SCLK - ensures plug-and-play integration with standard microcontroller SPI peripherals. |
Pinout & Package
The MAX1162CCUB+ is housed in a 10-pin µMAX® package (3mm × 3mm, 0.5mm pitch), RoHS-compliant and lead-free. Pin 3 and Pin 9 are both AGND and must be connected together at a star ground point.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 REF | External reference voltage input | Sets full-scale analog input range (0 to VREF); requires 4.7µF bypass to AGND for stable conversion accuracy. |
| 2 AVDD | Analog +5V supply | Must be bypassed to AGND with 0.1µF capacitor; powers analog core including T/H and SAR circuitry. |
| 3, 9 AGND | Analog ground | Dual ground pins - connect externally to minimize noise coupling into sensitive analog front-end. |
| 4 CS | Active-low chip select | High = shutdown (≤10µA); falling edge initiates conversion; rising edge disables DOUT (high-Z state). |
| 5 SCLK | Serial clock input | Drives conversion timing and data output; 100kHz–4.8MHz range; 50% duty cycle required at max frequency. |
| 6 DOUT | Serial data output | MSB-first unipolar output; transitions on SCLK falling edge; high-impedance when CS = high. |
| 7 DGND | Digital ground | Separate return path for digital logic; must be tied to system ground but isolated from AGND at single point. |
| 8 DVDD | Digital +2.7V to +5.25V supply | Enables direct interfacing with mixed-voltage logic; bypass to DGND with 0.1µF capacitor. |
| 10 AIN | Analog input | Unipolar input referenced to AGND; input capacitance = 40pF; protected by internal clamps (AGND − 0.3V to AVDD + 0.3V). |
Key Features
| Feature | Design Value |
|---|---|
| Adjustable logic level interface | DVDD supports +2.7V to +5.25V - eliminates level-shifting when interfacing with diverse microcontrollers and FPGAs. |
| Internal track-and-hold | 1.1µs acquisition time - reduces external buffering requirements and simplifies signal conditioning for DC and low-frequency AC inputs. |
| Low-noise analog front-end | 38µVRMS input-referred noise - preserves SNR > 87dB and SINAD > 86dB in precision sensor measurement chains. |
| AutoShutdown™ power control | 10µA shutdown current with <1.1µs wakeup - enables burst-mode sampling in energy-harvesting and wireless sensor nodes. |
| Small-footprint packaging | 10-pin µMAX (3mm × 3mm) - saves PCB area in compact industrial modules and handheld test equipment. |
Applications
| Motor Control | Industrial I/O Modules |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit SAR ADC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADS8325IPW | 16-bit, 100ksps, ±2 LSB INL, 3.3V-only DVDD, no internal T/H | Lower speed and narrower supply range; requires external T/H and reference buffer | Select for cost-sensitive, lower-throughput industrial sensors where 100ksps suffices and 3.3V-only logic is used. |
| AD7682BCPZ | 16-bit, 250ksps, ±1.5 LSB INL, 2.3–5.5V DVDD, internal T/H, SPI-compatible | Higher speed, tighter INL, wider DVDD range, but larger 20-lead LFCSP package | Select when ≥250ksps sampling or sub-2 LSB linearity is required, and PCB area allows 4mm × 4mm footprint. |
Compared with the MAX1162CCUB+, the ADS8325IPW trades speed and integration for lower cost and simpler power architecture, while the AD7682BCPZ offers superior linearity and throughput at the expense of larger size and higher unit price - making the MAX1162CCUB+ optimal for space-constrained 200ksps applications needing ±4 LSB INL and 10µA shutdown.

FAQ
What is the operating temperature range of the MAX1162CCUB+?
The MAX1162CCUB+ is specified for 0°C to +70°C ambient operation. Its ±4 LSB integral nonlinearity (INL) and 2.75mA supply current at 200ksps are guaranteed across this full range. This makes the MAX1162CCUB+ suitable for commercial and light-industrial environments where extended temperature grades are not required.
Does the MAX1162CCUB+ require an external reference voltage?
Yes, the MAX1162CCUB+ requires an external reference voltage applied to the REF pin. The reference must be between +3.8V and AVDD (up to +5.25V), and must be bypassed to AGND with a 4.7µF capacitor. The MAX1162CCUB+ does not include an internal reference; using a stable, low-noise reference is essential to achieve its specified 89.5dB SINAD and ±4 LSB INL performance.
Can the MAX1162CCUB+ interface directly with a 3.3V microcontroller?
Yes, the MAX1162CCUB+ supports direct interfacing with 3.3V logic through its separate DVDD supply pin, which accepts +2.7V to +5.25V. When DVDD = +3.3V, the digital inputs (CS, SCLK) recognize VIH ≥ 2.31V and VIL ≤ 0.99V, and DOUT drives VOH ≥ 3.05V and VOL ≤ 0.4V - fully compatible with standard 3.3V CMOS levels without level shifters.
What is the minimum acquisition time required before conversion starts on the MAX1162CCUB+?
The MAX1162CCUB+ has a fixed acquisition time of 1.1µs, defined as the interval from CS falling edge until the internal track-and-hold switches open. This time is independent of input source impedance below 1kΩ. For higher-impedance sources, the formula tACQ = 13(RS + 800Ω) × 35pF applies, but the device enforces a minimum 1.1µs acquisition window regardless.
How does the MAX1162CCUB+ handle power-down mode and wake-up?
The MAX1162CCUB+ enters power-down mode when CS is driven high, reducing total supply current to ≤10µA. Wake-up is immediate: a falling edge on CS reactivates the analog and digital circuitry, and the first conversion begins after the 1.1µs acquisition period. No additional delay or initialization sequence is needed - the MAX1162CCUB+ achieves full functionality within 1.1µs of CS assertion.
