Product details
Overview
MAX110BCPE from Maxim Integrated is a ±14-bit, 2-channel serial analog-to-digital converter (ADC) operating from ±5V supplies with differential input range of –3V to +3V. It delivers 0.03% linearity, 550µA active supply current, and 4µA power-down current, enabling high-resolution data acquisition in battery-powered industrial sensors and panel meters.
For engineers reviewing the MAX110BCPE datasheet, MAX110BCPE pinout, MAX110BCPE application, or MAX110BCPE equivalent, this device supports SPI/QSPI/MICROWIRE interfaces, features auto-calibration for offset/gain correction, and targets precision DC measurement systems requiring overrange detection and 50Hz/60Hz noise rejection.
Technical Context
The MAX110BCPE implements a first-order sigma-delta architecture with internal voltage-to-current conversion, integrator, comparator, and 1-bit DAC feedback loop. Its 16-bit serial output includes sign (POL), overrange (OFL), and 14 data bits in two's-complement format.
Conversion timing is programmable via CONV1–CONV4 control bits, supporting up to 50 conversions/sec. The device accepts either an external TTL/CMOS clock or uses its internal RC oscillator (selected via RCSEL), with oversampling clock division by 1, 2, or 4.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Resolution | ±14-bit + sign + overrange bit (16-bit serial output); enables precise DC signal digitization with overflow flagging |
| Linearity (INL) | ±0.03% FSR (typical); ensures accurate representation of analog inputs across full ±3V differential range |
| Supply Current | 550µA (active), 4µA (power-down); supports long-life operation in remote or portable instrumentation |
| Input Range | Differential ±3V (with ±5V supplies); accommodates wide-swing sensor outputs without external scaling |
| Rejection | 50Hz/60Hz notch filtering; suppresses mains interference in industrial process monitoring |
| Interface | SPI/QSPI/MICROWIRE-compatible serial I/O; reduces microcontroller pin count and simplifies opto-isolated designs |
| Calibration | Internal auto-calibration for offset and gain error under µP control; eliminates need for external trim components |
Pinout & Package
MAX110BCPE is housed in a 16-pin plastic DIP package (0°C to +70°C temperature grade). Pin functions are validated per Maxim's official datasheet Rev 5 (11/98).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN1+, IN1- | Differential Channel 1 Input | Accepts primary analog signal; supports ±3V differential range with common-mode tolerance |
| IN2+, IN2- | Differential Channel 2 Input | Enables dual-sensor or redundant measurement without external multiplexer |
| REF+, REF- | Differential Reference Inputs | Set full-scale range; VREF = VREF+ − VREF− must be ≤3V; determines LSB size (≈183µV at 3V ref) |
| CS | Chip Select | Active-low enable for serial interface; initiates conversion on rising edge when NO-OP = 1 |
| SCLK | Serial Clock Input | TTL/CMOS-compatible; controls data shift-in/out timing; supports DC to 2MHz operation |
| DIN | Serial Data Input | Loads 16-bit control word (NO-OP, CONV, CAL, PD, etc.) on SCLK rising edge |
| DOUT | Serial Data Output | Outputs 16-bit result (POL, OFL, D13–D0) on SCLK falling edge; high-impedance when CS high |
| BUSY | Conversion Status Flag | Active-low open-drain output; signals conversion progress; usable as µP interrupt |
| VDD, VSS | Power Supplies | +5V and –5V rails; absolute input voltage limits are VSS + 2.25V to VDD – 2.25V |
| RCSEL, XCLK | Oversampling Clock Control | RCSEL selects internal RC oscillator (VDD) or external clock (GND); XCLK routes clock source to sigma-delta modulator |
Key Features
| Feature | Design Value |
|---|---|
| No external components required | Self-contained calibration and reference path eliminate trimming resistors, capacitors, or op-amps |
| Auto-calibration mode | Microprocessor-controlled offset null and gain calibration reduce system-level drift without manual intervention |
| Two differential input channels | Hardware-multiplexed dual inputs simplify PCB layout and reduce BOM vs. discrete ADC + mux solutions |
| 50Hz/60Hz rejection | Integrated digital filtering rejects power-line interference without firmware-based averaging or external notch filters |
| Low-power shutdown | 4µA quiescent current in power-down mode extends battery life in intermittent-sampling applications |
Applications
| Process Control Sensor Interface | Weigh Scale Load Cell Digitization |
|---|---|
|
Use Scenario: Monitoring pressure, temperature, or flow transducers in PLC-connected field instruments. IC Role / Device Role / Timing Role: Primary ADC converting low-frequency analog outputs (e.g., 4–20mA loop receivers) into calibrated digital values for Modbus RTU transmission. Use Value: ±0.03% linearity and 50Hz rejection ensure stable readings in electrically noisy factory environments without additional filtering. |

IC Role / Device Role / Timing Role: Dual-channel ADC acquiring both main and auxiliary measurements (e.g., Vin and Iin) for real-time power calculation. Use Value: Two independent differential inputs avoid external analog switches, improving channel-to-channel isolation and reducing board area. |
Use Scenario: Long-term environmental sensing (temperature/humidity) in unattended outdoor nodes powered by coin-cell batteries. IC Role / Device Role / Timing Role: Low-power ADC activated periodically by µP to capture sensor data before returning to 4µA sleep state. Use Value: 4µA shutdown current enables multi-year operation on CR2032, while ±14-bit resolution preserves dynamic range for low-noise sensors. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar high-resolution serial ADC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADS1115IDGSR | 16-bit delta-sigma ADC, single-supply (+2.0V to +5.5V), integrated PGA (up to 16×), I²C interface | Requires I²C host; lacks native 50Hz/60Hz rejection; better suited for low-voltage, multi-gain sensor front-ends | Select when system uses I²C and needs programmable gain; not drop-in due to interface and supply differences |
| AD7705BRUZ | 16-bit sigma-delta ADC, ±2.5V reference, SPI interface, 1mW typical power, no internal oscillator | Requires external crystal/clock; lower linearity (±0.003% FSR) but higher effective resolution (20-bit noise-free) | Choose for ultra-low-noise DC measurements where external clock stability is available and power budget allows ~1mW |
Compared with MAX110BCPE, ADS1115IDGSR offers I²C simplicity and gain flexibility but sacrifices 50Hz rejection and dual-differential input capability; AD7705BRUZ provides superior noise performance and resolution but demands external timing and higher supply current, making MAX110BCPE optimal for cost-sensitive, mains-immune ±5V industrial DAQ.

FAQ
What is the operating temperature range for MAX110BCPE?
The MAX110BCPE is specified for 0°C to +70°C ambient operation. This commercial-grade temperature range is confirmed in the Ordering Information table of the datasheet, where "C" suffix denotes 0°C to +70°C, and "BCPE" packaging explicitly maps to this grade. The device maintains ±0.03% INL and 550µA supply current across this full range.
Does MAX110BCPE require external calibration components?
No, MAX110BCPE does not require external calibration components. Its internal auto-calibration circuitry corrects both offset and gain errors under microprocessor control, as stated in the General Description and Features sections. This eliminates the need for external trimpots, precision resistors, or reference buffers in the signal path.
What supply voltages does MAX110BCPE use?
MAX110BCPE operates from dual ±5V supplies: VDD = +5V and VSS = –5V. The Absolute Maximum Ratings specify VDD to GND ≤ +6V and VSS to GND ≥ –6V, and Electrical Characteristics are guaranteed at VDD = 5V ±5%, VSS = –5V ±5%. It is not compatible with single-supply operation.
How does the overrange (OFL) bit function in MAX110BCPE?
The overrange (OFL) bit in MAX110BCPE is the second bit shifted out (after POL) and indicates when the input voltage exceeds ±VREF. It functions correctly only if VREF remains within the recommended range (e.g., ≤3V for MAX110). The datasheet notes the converter does not saturate until input is ~20% beyond VREF, but linearity is not guaranteed in that region.
Can MAX110BCPE interface directly with an Arduino or similar MCU?
Yes, MAX110BCPE can interface directly with Arduino using its SPI-compatible serial interface. Connect CS, SCLK, DIN, DOUT, and BUSY to GPIO pins; configure the MCU to drive SCLK and sample DOUT on the falling edge. The 16-bit static shift register supports DC–2MHz clocks, and BUSY provides ready signaling-no level-shifting is needed for 5V-tolerant Arduinos.
