Product details
Overview
MAX1162BEUB from Maxim Integrated is a 16-bit successive-approximation analog-to-digital converter (ADC) with SPI/QSPI/MICROWIRE-compatible serial interface, 200ksps maximum sampling rate, ±2.5 LSB INL over –40°C to +85°C, and 10µA shutdown current. It operates from a single +5V analog supply while supporting digital logic levels from +2.7V to +5.25V, and is used in high-precision thermocouple and accelerometer measurement systems where low power and small footprint are critical.
For engineers reviewing the MAX1162BEUB datasheet, MAX1162BEUB pinout, MAX1162BEUB application, or MAX1162BEUB equivalent, this page delivers verified technical context, real-world design meaning of key specs, validated pin functions, and two confirmed alternative parts for industrial data-acquisition and battery-powered sensor interfaces.
Technical Context
The MAX1162BEUB integrates an internal track-and-hold with 4MHz input bandwidth and a capacitive DAC-based SAR architecture. Its conversion sequence is initiated by CS falling edge, requires 24 SCLK cycles (max 4.8MHz), and outputs 16-bit unipolar data preceded by eight leading zeros on DOUT.
It supports dual-supply operation: AVDD = +4.75V to +5.25V for analog circuitry and DVDD = +2.7V to +5.25V for digital I/O, enabling direct interfacing with mixed-voltage microcontrollers. AutoShutdown™ reduces total supply current to 0.1µA when CS is high, with 1.1µs wakeup time to full operation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Resolution | 16-bit - guarantees no missing codes across full operating temperature range (–40°C to +85°C) |
| Max Sampling Rate | 200ksps - enables real-time capture of signals up to 10kHz full-linear bandwidth (SINAD > 86dB) |
| INL Error | ±2.5 LSB - ensures end-point linearity accuracy suitable for precision industrial I/O modules |
| Supply Current @ 200ksps | 2.75mA (typ) - allows continuous high-speed acquisition in portable equipment with <3.3V/5V rail constraints |
| Shutdown Current | 10µA (max) - extends battery life in intermittent-sampling applications like wireless sensor nodes |
| SPI Clock Max Frequency | 4.8MHz - supports fast data transfer with minimal µC overhead; compatible with CPOL=0/CPHA=0 timing |
| Input Voltage Range | 0 to VREF - supports flexible full-scale configuration using external reference (3.8V to AVDD) |
Pinout & Package
MAX1162BEUB is housed in a 10-pin µMAX® package (3mm × 3mm, 0.5mm pitch), RoHS-compliant and lead-free. Pin functions are validated per Maxim's official datasheet (Rev 1, April 2010).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 REF | External reference voltage input | Sets full-scale analog input range; requires 4.7µF bypass to AGND for stable 16-bit accuracy |
| 2 AVDD | Analog +5V supply | Must be decoupled with 0.1µF capacitor to AGND; powers internal T/H and SAR core |
| 3, 9 AGND | Analog ground | Star grounding point; pins 3 and 9 must be connected together and tied to clean analog ground plane |
| 4 CS | Active-low chip select | Falling edge initiates conversion; high state forces AutoShutdown™ (10µA max current) |
| 5 SCLK | Serial clock input | Drives conversion timing and clocks out data; 4.8MHz max frequency, 40–60% duty cycle required |
| 6 DOUT | Serial data output | Three-state output (high-Z when CS = high); MSB-first format with eight leading zeros |
| 7 DGND | Digital ground | Separate from AGND to minimize digital noise coupling into analog path |
| 8 DVDD | Digital supply voltage | Accepts +2.7V to +5.25V; powers digital interface and output drivers |
| 10 AIN | Analog input | Single-ended input with 40pF capacitance; requires low-impedance source (<1kΩ) or buffer for full 16-bit performance |
Key Features
| Feature | Design Value |
|---|---|
| 16-bit resolution, no missing codes | Guaranteed monotonicity and full-code coverage across –40°C to +85°C operating range |
| Adjustable digital logic level | Supports DVDD from +2.7V to +5.25V - eliminates level-shifter need when interfacing with 3.3V or 5V µCs |
| Internal track-and-hold | 4MHz small-signal bandwidth enables accurate digitization of fast transients without external buffering |
| SPI/QSPI/MICROWIRE compatibility | Standard CPOL=0/CPHA=0 timing - simplifies firmware integration with common MCU peripheral libraries |

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 |
|---|---|---|---|
| ADS8860IDRCT | 16-bit, 1MSPS, single-supply 2.5–5.5V, no separate AVDD/DVDD rails; 1.75µA shutdown | Higher speed but lacks independent analog/digital supplies - less flexible for mixed-voltage systems | Prefer when system uses only one 3.3V rail and requires faster throughput; not drop-in due to different pinout and reference architecture |
| AD7960BCPZ | 18-bit, 5MSPS, differential input, LVDS interface, 2.5V supply only; 30µA shutdown | Higher resolution and speed, but requires differential driver and LVDS receiver - increases BOM and layout complexity | Choose for metrology-grade accuracy where 16-bit is insufficient; not suitable for space-constrained or low-cost industrial I/O |
Compared with ADS8860IDRCT and AD7960BCPZ, the MAX1162BEUB uniquely balances 16-bit precision, ultra-low shutdown current (10µA), independent AVDD/DVDD operation, and µMAX package size - making it optimal for battery-powered, mixed-voltage, and thermally demanding industrial sensor nodes where pin count and power budget are tightly constrained.

FAQ
What is the operating temperature range of the MAX1162BEUB?
The MAX1162BEUB is rated for –40°C to +85°C ambient operation, with guaranteed ±2.5 LSB integral nonlinearity across this full range. This extended temperature grade makes the MAX1162BEUB suitable for deployment in industrial control cabinets, outdoor instrumentation, and automotive under-hood sensor interfaces where thermal stability is critical to measurement integrity.
Does the MAX1162BEUB require an external reference voltage?
Yes, the MAX1162BEUB requires an external reference voltage applied to the REF pin, with a valid range of +3.8V to AVDD (up to +5.25V). A 4.7µF low-ESR capacitor must bypass REF to AGND to maintain 16-bit accuracy; omission causes increased noise and INL degradation. The MAX1162BEUB does not include an internal reference.
How does the MAX1162BEUB achieve 10µA shutdown current?
The MAX1162BEUB achieves 10µA shutdown current by driving the CS pin high, which disables internal analog circuitry including the track-and-hold amplifier and SAR logic while placing DOUT in high-impedance state. This AutoShutdown™ mode is specified at TA = +25°C and AVDD = DVDD = +5V, with typical current of 0.1µA - well within the 10µA max limit.
Can the MAX1162BEUB interface directly with a 3.3V microcontroller?
Yes, the MAX1162BEUB can interface directly with a 3.3V microcontroller: its DVDD accepts +2.7V to +5.25V, and digital inputs (CS, SCLK) recognize 0.7×DVDD as VIH - so at DVDD = 3.3V, VIH = 2.31V, safely met by standard 3.3V CMOS outputs. DOUT drives to DVDD – 0.25V, ensuring reliable logic-high recognition by the µC.
What is the minimum acquisition time required before a valid conversion on the MAX1162BEUB?
The MAX1162BEUB specifies a maximum acquisition time (tACQ) of 1.1µs - the time needed for its internal sampling capacitor to settle after CS fall. This value assumes source impedance ≤1kΩ; higher impedances increase tACQ per tACQ = 13(RS + 800Ω) × 35pF. For full 16-bit accuracy, the analog input must be stable for ≥1.1µs prior to the sixth SCLK edge.
