Product details
Overview
The MAX1188CCUP from Maxim Integrated is a 16-bit, 135ksps successive-approximation ADC with ±10V bipolar analog input range, single +4.75V to +5.25V analog supply, and byte-wide parallel interface. It features ±2 LSB INL, -100dB THD, and AutoShutdown™ reducing current to 0.4mA at 10ksps - ideal for precision industrial process control and medical instrumentation requiring high DC accuracy and low power.
For engineers reviewing the MAX1188CCUP datasheet, MAX1188CCUP pinout, MAX1188CCUP application, or MAX1188CCUP equivalent, this page delivers verified electrical specs, validated TSSOP-20 pin functions, confirmed ±10V input scaling architecture, and two field-tested alternative ADCs with documented performance trade-offs in industrial data-acquisition systems.
Technical Context
The MAX1188CCUP implements a SAR architecture with integrated track-and-hold and factory-trimmed internal +4.096V reference. Its input scaler enables true ±10V bipolar operation from a single +5V analog supply by attenuating and shifting the signal before the capacitive DAC stage.
Conversion is controlled via three CS edges: first edge powers up and initiates acquisition; second edge starts conversion and selects standby/shutdown mode via R/C; third edge loads 16-bit result onto D0–D15 bus, with HBEN toggling between high/low byte. EOC signals completion with 4.7µs max tCONV.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Resolution | 16-bit - delivers 65,536 distinct output codes for high-resolution measurement of small signal changes |
| Sampling Rate | 135ksps - supports real-time capture of signals up to ~60kHz Nyquist bandwidth |
| Analog Input Range | ±10V - accepts true bipolar industrial sensor outputs (e.g., ±10V strain gauge bridges) without external level-shifting |
| INL / DNL | ±2 LSB / ±1 LSB - ensures monotonicity and <0.003% full-scale linearity error for calibration-critical applications |
| THD | -100dB - suppresses harmonic distortion to enable clean spectral analysis in precision instrumentation |
| Supply Current | 2.9mA (ext ref) / 3.8mA (int ref) - enables battery-powered operation with AutoShutdown reducing current to 0.4mA between conversions |
| Operating Temp | 0°C to +70°C - qualified for commercial-grade embedded systems in controlled environments |
Pinout & Package
MAX1188CCUP is housed in a 20-pin TSSOP package (4.4mm × 6.5mm, 0.65mm pitch), optimized for space-constrained PCB layouts while maintaining thermal performance across the 0°C to +70°C range.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| D0/D8 – D7/D15 | Tri-state parallel data outputs | Byte-multiplexed 16-bit result: D0–D7 = LSB byte when HBEN = 0; D8–D15 = MSB byte when HBEN = 1 |
| R/C | Read/Convert control input | Three-edge function: sets acquisition start, selects standby/shutdown mode post-conversion, and triggers data load |
| EOC | End-of-conversion flag | Active-low open-drain signal indicating valid data ready on bus after tCONV = 4.7µs max |
| CS | Convert start strobe | Edge-triggered control: first falling edge powers up; second starts conversion; third loads data |
| HBEN | High-byte enable | Directs 16-bit output to either D0–D7 (low) or D8–D15 (high) - eliminates need for external byte latches |
| AIN | Analog input terminal | Accepts ±10V bipolar signal; internal scaler handles attenuation and offset - no external op-amp required for basic use |
| REF / REFADJ | Reference input/output pair | REF outputs +4.096V internal reference; REFADJ adjusts it or accepts external 3.8–4.2V source - bypassing critical for noise rejection |
| AVDD / DVDD | Separate analog/digital supplies | AVDD = +4.75V to +5.25V; DVDD = +2.7V to +5.25V - allows direct interfacing with 3.3V or 5V microcontrollers |
| AGND / DGND | Isolated ground returns | Must be connected at single point near device to prevent digital noise coupling into analog path |
Key Features
| Feature | Design Value |
|---|---|
| Bipolar ±10V input range | Enables direct connection to industrial sensors (e.g., load cells, RTDs with conditioning) without external level-shifting circuitry |
| Internal +4.096V reference | Factory-trimmed, ±35ppm/°C tempco, eliminates need for external precision reference in cost-sensitive designs |
| AutoShutdown™ mode | Reduces total supply current to 0.4mA at 10ksps - extends battery life in portable data loggers and handheld test equipment |
| Byte-wide parallel interface | Supports direct µP bus connection with minimal glue logic; HBEN simplifies 16-bit read timing in 8-bit microcontroller systems |

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, SPI interface, ±VREF input only (no built-in ±10V scaler); requires external reference and level-shifting for ±10V signals | Higher speed but lacks integrated input scaling - adds complexity for industrial ±10V sensor interfaces | Select when system demands >135ksps sampling and SPI bus compatibility outweighs need for simplified analog front-end design |
| AD7606C-16BSTZ | 16-bit, 1MSPS, simultaneous sampling of 8 channels, ±10V input supported via internal PGA; uses parallel or SPI interface | Multi-channel capability adds value in multi-sensor systems but increases cost and layout complexity vs. single-channel MAX1188CCUP | Select when acquiring synchronized data from multiple sensors (e.g., motor phase currents) justifies higher channel count and price premium |
Compared with ADS8860IDRCT and AD7606C-16BSTZ, the MAX1188CCUP provides unique integration of ±10V bipolar input scaling, internal reference, and byte-multiplexed parallel interface in a compact TSSOP-20 - reducing external component count and PCB area for single-channel, moderate-speed industrial DAQ.

FAQ
What is the maximum sampling rate of the MAX1188CCUP?
The MAX1188CCUP achieves a maximum sampling rate of 135ksps, with a guaranteed conversion time (tCONV) of 4.7µs maximum after entering hold mode. This rate supports accurate digitization of signals up to ~60kHz under Nyquist criteria, making the MAX1188CCUP suitable for medium-bandwidth industrial monitoring and test equipment applications where high resolution is prioritized over ultra-high speed.
Does the MAX1188CCUP require an external reference voltage?
No, the MAX1188CCUP includes a factory-trimmed internal +4.096V reference buffered at the REF pin, eliminating the need for an external reference in most applications. However, it also supports external references (3.8V–4.2V) applied to REF or REFADJ for enhanced stability or custom full-scale ranges - with REFADJ offering fine adjustment capability via sink/source current.
How does the MAX1188CCUP handle ±10V analog inputs with a +5V supply?
The MAX1188CCUP uses an integrated input scaler circuit that attenuates and level-shifts the ±10V input to match the internal DAC's range, enabling true bipolar operation from a single +4.75V to +5.25V analog supply. This eliminates external op-amps or resistor networks typically required for ±10V signal conditioning, simplifying design and improving noise immunity in industrial environments.
What is the purpose of the HBEN pin on the MAX1188CCUP?
The HBEN (High-Byte Enable) pin on the MAX1188CCUP controls multiplexing of the 16-bit conversion result onto the 8-bit parallel bus: when HBEN = 0, D0–D7 carry the LSB byte; when HBEN = 1, D8–D15 carry the MSB byte. This feature allows seamless interfacing with 8-bit microcontrollers without external byte latches or address decoding logic.
What power-saving modes does the MAX1188CCUP support?
The MAX1188CCUP supports two power-down modes selected via the R/C pin during the second CS falling edge: standby mode (reference and buffer remain active, 3.7mA typical current) for rapid successive conversions, and shutdown mode (reference and buffer powered down, 0.5µA typical current) for maximum energy savings between infrequent acquisitions - with 12ms wake-up time required for full 16-bit accuracy.
