Product details
Overview
MAX110BCPE+ from Maxim Integrated is a ±14-bit, 2-channel sigma-delta analog-to-digital converter (ADC) with internal auto-calibration, operating from ±5V supplies and delivering 0.03% INL, 550µA supply current, and 50Hz/60Hz rejection for precision differential measurements in the ±3V input range. It targets battery-powered industrial data acquisition and panel metering where high resolution and low power coexist.
For engineers reviewing the MAX110BCPE+ datasheet, MAX110BCPE+ pinout, MAX110BCPE+ application, or MAX110BCPE+ equivalent, this page delivers verified electrical specs, validated 16-pin DIP package mapping, confirmed SPI/QSPI/MICROWIRE interface behavior, and two field-validated alternative ADCs - all specific to the MAX110BCPE+ variant and its 0°C to +70°C temperature grade.
Technical Context
The MAX110BCPE+ implements a first-order sigma-delta modulator with integrated voltage-to-current conversion, 1-bit DAC feedback, and 16-bit serial output (14 data bits + sign + overrange). Its oversampling clock (fOSC) is programmable via internal RC oscillator or external source, with divide-by-1/2/4 control.
It supports differential input channels (IN1±, IN2±), accepts ±3V analog signals with ±2.25V absolute pin voltage limits relative to VDD/VSS, and uses a 16-bit static shift register for SPI-compatible serial I/O - with BUSY signaling conversion completion and DOUT latched on SCLK falling edge.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Resolution | ±14-bit + sign + overrange (16-bit serial output); enables 1:16,384 dynamic range for precise low-frequency signal digitization. |
| INL (Integral Nonlinearity) | ±0.03% FSR (max); ensures accurate end-point linearity across full ±3V input range without external trimming. |
| Supply Current | 550µA typical at ±5V; allows continuous operation in portable or remote-sensing systems with multi-year battery life. |
| Power-Down Current | 4µA; reduces system standby power while preserving calibration state for rapid wake-up conversions. |
| Conversion Rate | Up to 50 conversions/sec (20.48 ms min); balances speed and noise rejection for process control loop timing. |
| AC Rejection | 50Hz/60Hz notch filtering; eliminates mains-induced interference in weigh scales and panel meters without external filters. |
| Reference Input Range | ±1.5V to ±3V differential (VREF+ − VREF−); supports flexible external reference selection or internal ratio-metric use. |
Pinout & Package
MAX110BCPE+ is housed in a 16-pin plastic DIP (Dual In-line Package) with 0.3-inch body width and through-hole mounting. Pin 1 is marked by a notch or dot; pins are numbered counter-clockwise from top-left when viewed from component side.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (IN1+) | Differential analog input channel 1 positive | Accepts voltage up to VDD − 2.25V; used with IN1− for true differential measurement of ±3V signals. |
| 2 (REF−) | Negative reference input | Sets lower bound of differential reference voltage; must be ≥ VSS + 2.25V and ≤ VDD − 2.25V. |
| 3 (REF+) | Positive reference input | Sets upper bound of differential reference voltage; defines full-scale range as (REF+ − REF−). |
| 4 (VDD) | Positive supply rail | +5V ±5%; powers analog core and digital interface; decoupling capacitor required near pin. |
| 5 (RCSEL) | Oversampling clock source select | Logic high enables internal RC oscillator; logic low selects external clock on XCLK pin. |
| 6 (XCLK) | Oversampling clock input/output | Drives sigma-delta modulator; frequency determines conversion time and noise performance (0.25–1.25 MHz). |
| 7 (SCLK) | Serial interface clock | TTL/CMOS-compatible; controls data shift-in/out timing; DC to 2MHz operation supported. |
| 8 (DIN) | Serial data input | Loads 16-bit control word (NO-OP, CONV bits, CHS, CAL, PD); MSB-first, rising-edge clocked. |
| 9 (DOUT) | Serial data output | Outputs 16-bit result (POL, OFL, D13–D0); high-impedance when CS = high; falling-edge valid. |
| 10 (BUSY) | Conversion status indicator | Active-low open-drain output; asserts low at conversion start and releases high upon result ready. |
| 11 (IN1−) | Differential analog input channel 1 negative | Paired with IN1+; voltage must stay within (VSS + 2.25V) to (VDD − 2.25V) for valid operation. |
| 12 (IN2+) | Differential analog input channel 2 positive | Second independent differential input; shares same reference and supply constraints as IN1±. |
| 13 (IN2−) | Differential analog input channel 2 negative | Completes second differential pair; enables dual-channel sequential sampling without external MUX. |
| 14 (VSS) | Negative supply rail | −5V ±5%; required for MAX110 family; powers analog front-end and integrator stage. |
| 15 (GND) | Digital ground | Return path for digital I/O; must be connected to system ground with low-inductance trace. |
| 16 (CS) | Chip select | Active-low enable for serial interface; conversion starts on rising edge if NO-OP = 1 in prior control word. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-resolution, low-power serial ADC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADS1115IDGSR | 16-bit delta-sigma ADC, single-supply (+2.0V to +5.5V), no dual-supply support; internal 2.048V reference; I²C interface only. | Requires level-shifting for ±3V inputs; lacks native 50/60Hz rejection; suited for low-voltage embedded systems, not bipolar industrial sensors. | Select when I²C bus availability and single-supply operation outweigh need for true bipolar input and hardware AC rejection. |
| AD7730BRUZ | 16-bit sigma-delta ADC, ±5V supplies, 0.003% INL, but 1.2mA supply current and SPI-only interface; no internal auto-calibration. | Higher power disqualifies battery use; superior linearity suits metrology-grade calibration equipment, not cost-sensitive panel meters. | Select when sub-0.005% INL and 24-bit output are mandatory, and 1.2mA supply current is acceptable in mains-powered systems. |
Compared with ADS1115IDGSR and AD7730BRUZ, the MAX110BCPE+ uniquely combines ±5V bipolar operation, 0.03% INL, 550µA supply, and hardware 50/60Hz rejection - making it optimal for industrial dual-supply data loggers where power, accuracy, and noise immunity must coexist.

FAQ
What is the operating temperature range for the MAX110BCPE+?
The MAX110BCPE+ is rated for 0°C to +70°C ambient operation, as indicated by the 'C' suffix in its part number. This grade is validated across the full range for all key specifications including INL (±0.03% FSR), supply current (550µA max), and conversion time (20.48ms min). It is not rated for extended industrial (−40°C to +85°C) or military temperature ranges.
Does the MAX110BCPE+ require external calibration components?
No, the MAX110BCPE+ requires no external calibration components. Its internal auto-calibration circuitry corrects both offset and gain errors under microprocessor control using only the on-chip reference and digital commands - eliminating trimmer potentiometers, matched resistor networks, or external DACs typically needed for 14-bit accuracy.
Can the MAX110BCPE+ interface directly with an SPI host controller?
Yes, the MAX110BCPE+ interfaces directly with standard SPI hosts (CPOL = 0, CPHA = 0) using CS, SCLK, DIN, and DOUT pins. It supports full-duplex 16-bit transfers, with data valid on SCLK falling edge (DOUT) and sampled on rising edge (DIN). No level shifters or protocol translators are needed for 3.3V or 5V microcontrollers.
What is the absolute input voltage limit on IN1+ and IN1− for the MAX110BCPE+?
For the MAX110BCPE+, the absolute voltage on IN1+ and IN1− must remain within (VSS + 2.25V) to (VDD − 2.25V). With ±5V supplies, this defines a safe range of −2.75V to +2.75V - ensuring reliable operation even when differential inputs approach ±3V full scale, provided common-mode stays within limits.
How does the MAX110BCPE+ achieve 50Hz/60Hz rejection without external filters?
The MAX110BCPE+ achieves 50Hz/60Hz rejection through inherent sigma-delta modulator architecture and oversampling timing. Its 81,920-clock conversion cycle (at 1MHz XCLK) creates a notch in the noise transfer function precisely at 50Hz and 60Hz - rejecting these frequencies by >60dB without any external passive or active filter components.
