Product details
Overview
The MAX1162CCUB from Maxim Integrated is a 16-bit successive-approximation analog-to-digital converter (ADC) with single +5V analog supply, adjustable digital logic level (+2.7V to +5.25V), 200ksps maximum sampling rate, ±4 LSB integral nonlinearity at 0°C to +70°C, and 10µA shutdown current. It serves as a precision data-acquisition front-end in space-constrained, battery-powered industrial sensor interfaces.
For engineers reviewing the MAX1162CCUB datasheet, MAX1162CCUB pinout, MAX1162CCUB application, or MAX1162CCUB equivalent, key selection criteria include its 1.1µs track/hold acquisition time, SPI/QSPI/MICROWIRE-compatible serial interface, 4MHz input bandwidth, and µMAX-10 package compatibility with tight PCB layout constraints.
Technical Context
The MAX1162CCUB implements a capacitive DAC-based SAR architecture with internal track-and-hold, supporting unipolar 0–VREF input range and requiring external reference voltage (3.8V to AVDD). Its conversion sequence is initiated by CS falling edge and clocked by SCLK up to 4.8MHz, outputting 8 leading zeros followed by 16 MSB-first data bits on DOUT.
Power management is controlled via CS: high state enables AutoShutdown™ mode (≤10µA total supply current), while low state activates full operation (2.75mA at 200ksps). Analog and digital supplies are independent (AVDD = 4.75–5.25V, DVDD = 2.7–5.25V), enabling direct interfacing with mixed-voltage microcontrollers.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Resolution | 16-bit - guarantees no missing codes for full-scale linear measurement integrity |
| Max Sampling Rate | 200ksps - supports real-time capture of signals up to 10kHz full-linear bandwidth (SINAD > 86dB) |
| INL (0°C to +70°C) | ±4 LSB - defines end-point linearity error over full temperature range for this variant |
| Shutdown Current | 10µA - enables ultra-low-power sleep between measurements in portable equipment |
| Input Bandwidth | 4MHz - allows accurate digitization of fast transients and undersampling applications |
| Reference Range | 3.8V to AVDD - supports flexible external reference selection including 4.096V standard references |
| Serial Interface | SPI/QSPI/MICROWIRE-compatible - interoperable with common MCU peripheral modes (CPOL=0, CPHA=0) |
Pinout & Package
MAX1162CCUB is housed in a lead(Pb)-free, RoHS-compliant 10-pin µMAX® package (3mm × 3mm, 0.8mm height), optimized for high-density PCB layouts in portable instrumentation.
| 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 stability |
| 2 AVDD | Analog +5V supply | Must be bypassed to AGND with 0.1µF capacitor; powers internal T/H and SAR core |
| 3, 9 AGND | Analog ground | Star grounding point; pins 3 and 9 must be connected together near AVDD bypass |
| 4 CS | Active-low chip select | Falling edge initiates conversion; high state forces AutoShutdown™ (≤10µA) |
| 5 SCLK | Serial clock input | Drives conversion timing and data shift-out; supports 100kHz–4.8MHz (50% duty cycle) |
| 6 DOUT | Serial data output | Three-state, MSB-first output; high-impedance when CS = high |
| 7 DGND | Digital ground | Isolated from AGND except at system-level star point; minimizes digital noise coupling |
| 8 DVDD | Digital supply voltage | Accepts +2.7V to +5.25V; enables direct interface with 3.3V or 5V logic families |
| 10 AIN | Analog input | Unipolar input (0 to VREF); 40pF input capacitance requires low-impedance drive or buffer |
Key Features
| Feature | Design Value |
|---|---|
| 16-bit no-missing-codes resolution | Ensures monotonicity and full-scale linearity for precision measurement systems without calibration gaps |
| 1.1µs track/hold acquisition time | Enables high-throughput sampling with minimal dead time between conversions |
| Adjustable digital I/O voltage (2.7V–5.25V) | Eliminates level-shifting components when interfacing with 3.3V microcontrollers |
| Internal track-and-hold with 4MHz bandwidth | Supports accurate digitization of fast-rising signals without external buffering in many cases |
| AutoShutdown™ with ≤10µA current | Extends battery life in portable data loggers by reducing quiescent power during idle intervals |

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, SPI interface, 2.7V–5.5V supply, ±1.5 LSB INL, no internal T/H | Lower speed and higher linearity; requires external track/hold for >100ksps use | Select when absolute linearity (<±2 LSB) outweighs speed and integrated T/H convenience |
| AD7682BCPZ | 16-bit, 250ksps, SPI interface, 2.3V–5.5V supply, ±1.5 LSB INL, pseudo-differential inputs | Higher speed and better linearity; different input structure (pseudo-diff vs. true single-ended) | Select when differential signaling or >200ksps throughput is required; verify layout compatibility with CPZ package |
Compared with ADS8325IPW and AD7682BCPZ, the MAX1162CCUB offers integrated track/hold and lowest shutdown current (10µA), making it optimal for battery-powered, space-constrained single-ended measurement systems where 200ksps and ±4 LSB INL are sufficient.

FAQ
What is the operating temperature range for the MAX1162CCUB?
The MAX1162CCUB is specified for 0°C to +70°C ambient operation. This commercial-grade temperature range aligns with its ±4 LSB integral nonlinearity specification and supports use in indoor industrial equipment, portable test gear, and non-automotive embedded systems where extended thermal margins are not required. The MAX1162CCUB datasheet confirms this range in the Ordering Information table.
Does the MAX1162CCUB require an external reference voltage?
Yes, the MAX1162CCUB requires an external reference voltage applied to the REF pin. It accepts 3.8V to AVDD (up to +5.25V), with typical operation at +4.096V. The reference must be bypassed with a 4.7µF capacitor to AGND, and its output impedance must be ≤10Ω to maintain DC accuracy. The MAX1162CCUB does not include an internal reference.
What package type is used for the MAX1162CCUB?
The MAX1162CCUB uses the 10-pin µMAX® package (3mm × 3mm, 0.8mm height), a lead(Pb)-free, RoHS-compliant surface-mount package. This is confirmed in the Ordering Information table where "CCUB+" denotes the µMAX variant. The µMAX package provides thermal and electrical performance comparable to DFN but with distinct pinout and land pattern requirements.
How does the MAX1162CCUB enter shutdown mode?
The MAX1162CCUB enters shutdown mode when the CS pin is driven high. In this state, total supply current drops to ≤10µA (typical), and the DOUT pin enters high-impedance. A falling edge on CS exits shutdown and initiates conversion. This AutoShutdown™ behavior is intrinsic to the MAX1162CCUB's design and requires no additional control signals or configuration registers.
Can the MAX1162CCUB interface directly with a 3.3V microcontroller?
Yes, the MAX1162CCUB supports direct interface with 3.3V microcontrollers via its independent DVDD supply (2.7V–5.25V range) and CMOS-compatible digital inputs. SCLK and CS accept 0.7×DVDD high-level thresholds, and DOUT drives to DVDD – 0.25V high level-fully compatible with 3.3V logic without level shifters. This capability is explicitly stated in the Electrical Characteristics table under Digital Inputs and Outputs.
