Product details
Overview
MAX1062CCUB+ from Maxim Integrated is a 14-bit successive-approximation analog-to-digital converter (ADC) with ±3 LSB integral nonlinearity, 200ksps maximum sampling rate, and 10µA shutdown current. It operates from a single +5V analog supply while supporting 2.7V–5.25V digital logic levels, and is used in portable data-acquisition systems requiring high resolution and ultra-low standby power.
For engineers reviewing the MAX1062CCUB+ datasheet, MAX1062CCUB+ pinout, MAX1062CCUB+ application, or MAX1062CCUB+ equivalent, this page delivers verified electrical specs, real-world timing behavior, µMAX package layout, and validated alternatives for industrial I/O, thermocouple measurement, and battery-powered sensor interfaces.
Technical Context
The MAX1062CCUB+ implements a SAR architecture with internal track-and-hold, enabling 4MHz small-signal input bandwidth and 1.1µs acquisition time. Its serial interface supports SPI/QSPI/MICROWIRE protocols at up to 4.8MHz with CPOL=0/CPHA=0 configuration and outputs 14-bit unipolar data preceded by eight leading zeros.
Power management is controlled via active-low CS: asserting CS high places the device in AutoShutdown™ mode (≤10µA total supply current), while CS falling edge initiates conversion. The ADC accepts external reference voltages from 3.8V to AVDD and features separate analog/digital supplies with independent ground pins (AGND ×2, DGND).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Resolution | 14-bit - delivers 16,384 discrete output codes for precision measurement applications |
| Sampling Rate | 200ksps max - supports real-time capture of signals up to 20kHz full-linear bandwidth (SINAD >81dB) |
| INL | ±3 LSB - defines end-point linearity error across full scale; impacts absolute accuracy in calibration-critical systems |
| Supply Current | 2.75mA at 200ksps - enables low-power operation without sacrificing throughput in embedded DAQ |
| Shutdown Current | ≤10µA - allows extended battery life during idle periods in portable instrumentation |
| SINAD | 81dB typical (1kHz, 4.096Vp-p) - determines effective resolution (~13.2 bits) under dynamic signal conditions |
| Input Bandwidth | 4MHz - permits faithful digitization of fast transients and undersampling of higher-frequency periodic signals |
Pinout & Package
MAX1062CCUB+ is housed in a 10-pin µMAX® package (3mm × 3mm, 0.5mm pitch), optimized for space-constrained PCB layouts in portable equipment. Pin 1 is REF; pins 3 and 9 are AGND (must be connected together); pin 7 is DGND; pin 10 is AIN.
| 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 noise immunity |
| 2 AVDD | Analog +5V supply | Must be decoupled to AGND (pin 3) with 0.1µF capacitor; powers internal T/H and SAR core |
| 3, 9 AGND | Analog ground | Star grounding point; both pins must be tied together and connected to system analog ground plane |
| 4 CS | Active-low chip select | Falling edge initiates conversion; high state forces shutdown (≤10µA current) |
| 5 SCLK | Serial clock input | Drives conversion and clocks out data; supports 100kHz–4.8MHz with 40–60% duty cycle |
| 6 DOUT | Serial data output | Three-state output (high-Z when CS high); MSB-first format with eight leading zeros |
| 7 DGND | Digital ground | Isolated from AGND to minimize digital noise coupling into analog path |
| 8 DVDD | Digital supply (2.7V–5.25V) | Enables direct interfacing with mixed-voltage microcontrollers and FPGAs |
| 10 AIN | Analog input | Unipolar input referenced to AGND; protected by internal clamps (AGND−0.3V to AVDD+0.3V) |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar 14-bit SAR ADC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADS8325IPW | 16-bit resolution, 100ksps max, SPI-only interface, 2.7V–5.5V supply | Higher resolution but lower speed; lacks QSPI/MICROWIRE compatibility | Select when absolute accuracy >14-bit is required and 100ksps suffices |
| AD7940BRMZ | 14-bit, 100ksps, 2.7V–5.25V supply, no internal T/H, requires external driver | No integrated track-and-hold; needs external op-amp for full-bandwidth performance | Choose when board space allows external buffering and lower cost is prioritized |
Compared with MAX1062CCUB+, ADS8325IPW offers greater resolution at half the speed and narrower interface compatibility, while AD7940BRMZ reduces integration but increases BOM count and layout complexity due to missing internal T/H.

FAQ
What is the maximum sampling rate of the MAX1062CCUB+ and what conditions apply?
The MAX1062CCUB+ achieves a maximum sampling rate of 200ksps under specified conditions: AVDD = DVDD = +4.75V to +5.25V, fSCLK = 4.8MHz (50% duty cycle), 24 clocks per conversion, and VREF = +4.096V. At this rate, typical analog supply current is 2.75mA and digital supply current is 0.6mA. Reducing clock frequency below 100kHz may degrade DC accuracy due to leakage effects.
How does the MAX1062CCUB+ achieve its 10µA shutdown current, and what is the wake-up time?
The MAX1062CCUB+ enters shutdown mode when CS is driven high, reducing total supply current to ≤10µA (typical 0.1µA). Wake-up occurs on the falling edge of CS, with full functionality restored in 1.1µs - matching the track-and-hold acquisition time. This fast wake-up enables burst-mode operation ideal for intermittent sensing in battery-powered devices.
What are the key timing requirements for the serial interface of the MAX1062CCUB+?
The MAX1062CCUB+ requires SCLK pulse widths ≥65ns (high and low), period ≥208ns (4.8MHz max), and CS pulse width ≥50ns. CS must remain low for ≥24 SCLK cycles to complete one conversion. SCLK-to-DOUT valid delay is ≤100ns (CDOUT = 50pF), and CS rise-to-DOUT disable is ≤80ns. Duty cycle must stay between 40% and 60% at maximum frequency.
Can the MAX1062CCUB+ interface directly with a 3.3V microcontroller, and how is level compatibility ensured?
Yes - the MAX1062CCUB+ supports DVDD from 2.7V to 5.25V, allowing direct connection to 3.3V logic. Digital inputs (CS, SCLK) accept VIH ≥0.7×DVDD and VIL ≤0.3×DVDD; DOUT drives VOH ≥DVDD−0.25V and VOL ≤0.4V at 1.6mA sink. No level shifters are needed when DVDD = 3.3V, simplifying interface design with modern MCUs.
What is the significance of the ±3 LSB INL specification for the MAX1062CCUB+ in practical applications?
The ±3 LSB integral nonlinearity (INL) of the MAX1062CCUB+ means the deviation from the ideal transfer function never exceeds ±3 codes across its full 14-bit range. This translates to <±0.018% full-scale error, making it suitable for applications like thermocouple linearization and industrial I/O where end-point calibration is performed but fine-grained correction tables are impractical.
