Product details
Overview
MAX1167BCEE+ from Maxim Integrated is a 16-bit, 4-channel, 200ksps successive-approximation ADC with integrated +4.096V reference, internal oscillator, and SPI/QSPI/MICROWIRE-compatible serial interface. It operates from a single +5V analog supply and supports digital logic levels from +2.7V to +5.5V. Designed for precision data acquisition in space-constrained industrial control systems, it delivers ±3 LSB INL, 88.5 dB SINAD, and 4 MHz input bandwidth.
For engineers reviewing the MAX1167BCEE+ datasheet, MAX1167BCEE+ pinout, MAX1167BCEE+ application, or MAX1167BCEE+ equivalent, this page provides verified technical context, real-world use cases, validated alternatives, and supply-chain support tailored for embedded industrial design and motor control BOMs.
Technical Context
The MAX1167BCEE+ implements a fully integrated SAR architecture with on-chip track-and-hold, internal reference buffer, and auto-power-down logic. Its 4-channel analog multiplexer feeds into a single 16-bit conversion core, supporting both external clock (up to 9 MHz SCLK) and internal 4 MHz oscillator operation.
It features dual power domains (AVDD = +4.75V to +5.25V, DVDD = +2.7V to +5.25V), scan-mode sequencing across all four inputs, and programmable shutdown modes yielding ≤0.6 µA current draw. The device guarantees operation over 0°C to +70°C and uses a 16-pin QSOP package with defined AGND/DGND separation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Resolution | 16-bit, no missing codes - ensures monotonicity and full-scale linearity across temperature. |
| Sampling Rate | 200 ksps maximum - enables real-time capture of fast transients in motor current sensing. |
| INL | ±3 LSB - defines absolute accuracy error bound for calibration-critical thermocouple measurement. |
| SINAD | 88.5 dB typical - supports >14.4 ENOB for high-fidelity signal reconstruction in vibration monitoring. |
| Input Bandwidth | 4 MHz - allows undersampling of RF-modulated sensor outputs without aliasing if filtered. |
| Supply Current | 3.6 mA at 200 ksps (AVDD = DVDD = +5V) - enables low-power operation in battery-backed DAQ modules. |
| Reference | +4.096 V internal (±25 ppm/°C TC) - eliminates external reference component and layout area. |
Pinout & Package
MAX1167BCEE+ is housed in a 16-pin QSOP (Quad Small Outline Package) with 0.154" body width and 0.025" lead pitch. Pin 1 is marked by a dot; pin numbering follows standard counterclockwise orientation from the index mark.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | DOUT | Serial data output - tri-state when CS high; MSB-first unipolar format synchronized to SCLK falling edge. |
| 2 | SCLK | Serial clock input - drives conversion timing and data transfer; supports up to 9 MHz external clock. |
| 3 | DIN | Serial command input - loads configuration bits (e.g., channel select, power mode) on SCLK rising edge. |
| 4 | EOC | End-of-conversion flag - active-low pulse in internal clock mode; remains high during external clock operation. |
| 5–8 | AIN0–AIN3 | Analog input channels - single-ended, 0 V to VREF range; each internally multiplexed to SAR core. |
| 9 | REF | Reference voltage node - accepts internal +4.096 V or external 3.8 V to AVDD–0.2 V; requires 10 µF bypass. |
| 10 | REFCAP | Internal reference bypass - connects to 0.1 µF capacitor to AGND only when using internal reference. |
| 11,12 | AGND | Analog ground return - star-connected to AVDD decoupling; must be isolated from DGND except at single point. |
| 13 | AVDD | Analog supply - +4.75 V to +5.25 V; powers SAR core, T/H, and reference; requires 0.1 µF local bypass. |
| 14 | CS | Active-low chip select - initiates conversion on high-to-low transition; forces 0.6 µA shutdown when held high. |
| 15 | DGND | Digital ground - return path for DVDD; kept separate from AGND to minimize digital noise coupling. |
| 16 | DVDD | Digital supply - +2.7 V to +5.25 V; powers interface logic; independent of AVDD for mixed-voltage system interfacing. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated +4.096 V reference | Eliminates external reference IC and reduces PCB area by ≥3 components in compact I/O modules. |
| AutoShutdown™ power management | Reduces current to 185 µA at 10 ksps and <10 µA at lower rates - extends runtime in portable DAQ devices. |
| 4 MHz analog input bandwidth | Supports accurate digitization of fast-switching motor phase currents without external amplification. |
| SPI/QSPI/MICROWIRE compatibility | Direct interface to ARM Cortex-M, Renesas RX, and TI C2000 microcontrollers without level-shifting or glue logic. |
| Scan mode with sequential conversion | Automatically cycles through AIN0–AIN3 with configurable inter-conversion delay - simplifies firmware for multi-sensor polling. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit multichannel ADC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADS8684IPWR | 4-channel, 16-bit, 500 ksps SAR ADC with ±10.24 V input range and integrated PGA; requires external reference. | Better suited for bipolar or high-voltage industrial sensors; larger 28-pin TSSOP package increases board area. | Select when input signals exceed 0–4.096 V range or require programmable gain amplification before conversion. |
| AD7682BCPZ-RL7 | 4-channel, 16-bit, 250 ksps SAR ADC with internal 2.5 V reference; no integrated oscillator; SPI-only interface. | Lacks AutoShutdown™ and scan mode; higher 6.5 mA active current limits battery-powered use. | Choose for cost-sensitive designs where reference voltage stability is less critical and firmware handles channel sequencing. |
Compared with ADS8684IPWR and AD7682BCPZ-RL7, the MAX1167BCEE+ uniquely combines integrated +4.096 V reference, internal oscillator, AutoShutdown™, and scan-mode automation - reducing BOM count, power budget, and firmware overhead in compact industrial DAQ systems.

FAQ
What is the operating temperature range for MAX1167BCEE+?
The MAX1167BCEE+ is specified for the commercial temperature range of 0°C to +70°C. This is confirmed by the Ordering Information table listing "MAX1167BCEE" with "0°C to +70°C" under TEMP RANGE. It is not rated for extended industrial temperatures (–40°C to +85°C), which apply to the MAX1167BEEE variant.
Does MAX1167BCEE+ support internal reference operation?
Yes, MAX1167BCEE+ integrates a factory-trimmed +4.096 V reference with ±25 ppm/°C temperature coefficient and 5 ms wake-up time. When enabled, REF and REFCAP pins must be bypassed with 10 µF and 0.1 µF capacitors to AGND respectively - no external reference IC is required for standard 0–4.096 V input ranges.
How many analog input channels does MAX1167BCEE+ have?
MAX1167BCEE+ has four single-ended analog input channels: AIN0, AIN1, AIN2, and AIN3. This is explicitly stated in the General Description ("The MAX1167 includes a 4-channel input multiplexer") and confirmed in the Pin Description table showing pins 5–8 assigned to those inputs.
What serial interface protocols is MAX1167BCEE+ compatible with?
MAX1167BCEE+ supports SPI, QSPI, and MICROWIRE-compatible 3-wire serial communication using CS, SCLK, and DIN/DOUT. It does not support I²C or UART. The interface operates in both external-clock and internal-clock modes, with EOC signaling end-of-conversion in internal-clock mode.
What is the minimum acquisition time for MAX1167BCEE+?
The minimum acquisition time for MAX1167BCEE+ is 729 ns under external clock conditions, as specified in the Electrical Characteristics table. This value is guaranteed across temperature and supply voltage, and assumes source impedance ≤200 Ω; higher impedances increase required acquisition time per the tACQ formula in the datasheet.
