Product details
Overview
MAX110BCWE+T from Maxim Integrated is a ±14-bit, 2-channel serial analog-to-digital converter (ADC) with internal auto-calibration, operating from ±5V supplies and delivering 0.03% linearity over -3V to +3V differential input range. It consumes only 550µA active current and drops to 4µA in power-down mode, enabling high-resolution battery-powered data acquisition in weigh scales and panel meters.
For engineers reviewing the MAX110BCWE+T datasheet, MAX110BCWE+T pinout, MAX110BCWE+T application, or MAX110BCWE+T equivalent, this device supports SPI/QSPI/MICROWIRE interfaces, offers 50Hz/60Hz rejection, and delivers calibrated 14-bit resolution plus sign and overrange bits without external components - critical for precision industrial sensing where supply stability and noise immunity are essential.
Technical Context
The MAX110BCWE+T implements a first-order sigma-delta architecture with integrated voltage-to-current converter, integrator, comparator, and 1-bit DAC to generate pulse-width-modulated output averaged into 16-bit serial data (14 data + sign + overrange). Its internal auto-calibration corrects both offset and gain errors under µP control.
It supports dual differential inputs (IN1±, IN2±), accepts ±5V supplies, uses an oversampling clock (fOSC) configurable via divide-by-1/2/4, and provides programmable conversion time (10,240–102,400 clocks/conv) - enabling trade-offs between speed (up to 50 conversions/sec) and noise rejection.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Resolution | 14-bit + sign + overrange bit (16-bit serial output); ensures unambiguous polarity and overflow detection in ±3V input range. |
| Linearity (INL) | ±0.03% FSR (max); guarantees monotonicity and <0.5 LSB error across full scale for precision measurement. |
| Supply Current | 550µA (active), 4µA (power-down); enables multi-year operation on coin-cell batteries in remote sensors. |
| Differential Input Range | ±3V (with ±5V supplies and VREF = ±1.5V); matches industrial transducer outputs without signal conditioning. |
| Conversion Rate | Up to 50 conversions/sec (at minimum clock cycles); sufficient for slow-varying process variables like temperature or pressure. |
| Power-Supply Rejection | 30 ppm/V (typical); maintains accuracy despite ±5% supply variation in unregulated systems. |
| 50/60Hz Rejection | Integrated digital filtering rejects mains interference without external notch filters or software averaging. |
Pinout & Package
MAX110BCWE+T is housed in a 16-pin Wide SO (SOIC-W) package, 7.5mm × 10.3mm body, 1.27mm pitch, RoHS-compliant, with exposed pad option not specified.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN1+, IN1- | Differential Analog Input Channel 1 | Accepts ±3V differential signal; common-mode range constrained to (VSS + 2.25V) to (VDD – 2.25V). |
| IN2+, IN2- | Differential Analog Input Channel 2 | Second independent differential input; shares same reference and calibration as IN1±. |
| REF+, REF- | Differential Reference Input | Sets full-scale range (VREF = VREF+ – VREF-); supports up to ±1.5V for ±3V input span. |
| VDD, VSS | Positive/Negative Power Supplies | Require ±5V ±5%; VSS must be ≤ –4.75V for guaranteed performance per datasheet limits. |
| CS, SCLK, DIN, DOUT | Serial Interface Control/Data | Standard SPI-compatible signals; DOUT is three-state; CS initiates read/write and triggers conversion on rising edge. |
| BUSY | Conversion Status Output | Active-low open-drain signal indicating conversion in progress; used for interrupt-driven µP synchronization. |
| RCSEL, XCLK | Oversampling Clock Source Control | RCSEL selects internal RC oscillator (VDD) or external clock (GND); XCLK routes clock source to sigma-delta modulator. |
Key Features
| Feature | Design Value |
|---|---|
| Internal Auto-Calibration | Corrects offset and gain errors under µP command - eliminates manual trim pots and factory calibration steps. |
| No External Components Required | Full 14-bit performance achieved with only decoupling caps; reduces BOM count and PCB area in space-constrained designs. |
| 50Hz/60Hz Rejection | Hardware-based digital filtering removes mains-frequency noise without firmware overhead or sampling-rate constraints. |
| Two Differential Input Channels | Enables simultaneous monitoring of two isolated sensor signals (e.g., load cell + temperature) with shared reference and timing. |
| Low-Power Power-Down Mode | 4µA shutdown current allows microcontroller to wake ADC only when measurement is needed - extending battery life significantly. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 14-bit serial ADC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADS1115IDGSR | Single-supply (+2.0V to +5.5V), I²C interface, 16-bit resolution, no internal reference; requires external VREF for full accuracy. | Designed for low-voltage, low-pin-count embedded systems; lacks 50/60Hz rejection and auto-calibration. | Select when I²C bus availability and ultra-low supply voltage (<3V) outweigh need for mains-noise immunity and self-calibration. |
| AD7705BRUZ | ±2.5V supply range, 16-bit sigma-delta, SPI interface, on-chip PGA (1–128×), but no overrange bit or sign bit in default mode. | Optimized for low-level sensor signals requiring programmable gain; higher power (1mW active) and larger 24-pin TSSOP package. | Select when variable gain amplification is required pre-ADC and ±5V dual supply is unavailable. |
Compared with ADS1115IDGSR and AD7705BRUZ, the MAX110BCWE+T uniquely combines ±5V dual-supply operation, hardware 50/60Hz rejection, and auto-calibration in a 16-pin SO package - making it optimal for legacy industrial systems requiring drop-in compatibility with existing ±5V rails and noise-prone AC environments.

FAQ
What is the operating temperature range for the MAX110BCWE+T?
The MAX110BCWE+T is rated for 0°C to +70°C ambient operation, as indicated by the "C" grade suffix in its part number. This commercial-grade temperature range is validated per Maxim's production test flow and applies to all electrical specifications in the datasheet unless otherwise noted. The MAX110BCWE+T maintains ±0.03% INL and 550µA supply current across this full range, with no derating required.
Does the MAX110BCWE+T require external calibration components?
No, the MAX110BCWE+T does not require external calibration components. Its internal auto-calibration circuitry corrects both offset and gain errors under microprocessor control using only the on-chip reference and logic - eliminating trim pots, external references, or factory calibration steps. This capability is intrinsic to the MAX110BCWE+T design and functions identically across all units in the 0°C to +70°C range.
Can the MAX110BCWE+T operate with a single +5V supply?
No, the MAX110BCWE+T requires dual ±5V supplies (VDD = +5V, VSS = –5V) and cannot operate from a single +5V rail. Its analog input range is ±3V differential, which necessitates negative supply headroom for proper common-mode operation. Attempting single-supply use violates absolute maximum ratings and will result in incorrect conversion or device damage. For single-supply applications, consider the pin-compatible MAX111 series instead.
What is the function of the BUSY pin on the MAX110BCWE+T?
The BUSY pin on the MAX110BCWE+T is an active-low, open-drain output that goes low at the start of conversion and returns high upon completion. It provides hardware synchronization for microcontrollers - allowing interrupt-driven data reads without polling. The MAX110BCWE+T's BUSY signal remains asserted for the full synchronous conversion time (e.g., 204.8ms at 102,400 clocks/conv), ensuring precise timing alignment with the serial interface.
How does the MAX110BCWE+T achieve 50Hz/60Hz rejection?
The MAX110BCWE+T achieves 50Hz/60Hz rejection through inherent sigma-delta oversampling combined with programmable conversion timing. By selecting clock cycles per conversion that are integer multiples of 100ms (for 10Hz) or 83.3ms (for 12Hz), the modulator's noise-shaping and digital filtering naturally attenuate mains-frequency interference - no external filters or firmware averaging required. This rejection is specified and tested per the MAX110BCWE+T datasheet under standard operating conditions.
