Product details
Overview
ADC0832CCWM/NOPB from Texas Instruments is an 8-bit successive-approximation analog-to-digital converter with a 2-channel software-configurable multiplexer, serial MICROWIRE-compatible interface, ±1 LSB total unadjusted error, 32 μs conversion time, and single 5 VDC supply operation. It supports single-ended or differential input configurations and is used in embedded sensor signal conditioning where compact serial ADCs replace parallel interfaces.
For engineers reviewing the ADC0832CCWM/NOPB datasheet, ADC0832CCWM/NOPB pinout, ADC0832CCWM/NOPB application, or ADC0832CCWM/NOPB equivalent, key selection considerations include its 2-channel MUX flexibility, ratiometric reference capability, SOIC-8 package compatibility, and absence of zero/full-scale trim requirements in cost-sensitive industrial monitoring systems.
Technical Context
The ADC0832CCWM/NOPB implements a sample-data comparator architecture with a resistor ladder DAC for successive approximation. Its 2-channel multiplexer is software-addressed via a 3-bit shift sequence (start bit + 2 address bits) on the DI line prior to conversion initiation.
It features a tri-state DO output supporting both MSB-first and LSB-first data formats (via SE pin), TTL/MOS-compatible logic levels, and internal shunt regulation enabling operation from V+ up to 8.5 V while maintaining VCC within safe limits. The device operates over 0°C to +70°C and requires no external zero or full-scale calibration.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Resolution | 8 bits - delivers 256 discrete digital codes across full-scale input range |
| Total Unadjusted Error | ±1 LSB - includes offset, full-scale, linearity, and multiplexer errors; no trimming required |
| Conversion Time | 32 μs - fixed duration at fCLK = 250 kHz; enables up to ~31.25 kSPS throughput |
| Supply Voltage | 4.5 V to 6.3 V - supports standard 5 V rail and tolerates minor variation without performance loss |
| Input Range | 0 V to 5 V - ratiometric operation with VREF = VCC; accepts inputs from GND to VCC + 0.05 V |
| Power Dissipation | 15 mW at 5 V - low quiescent current (2.3 mA typical ICC) suitable for battery-aware designs |
| Reference Input | Internally tied to VCC - eliminates external reference component in ratiometric applications |
Pinout & Package
ADC0832CCWM/NOPB is housed in an 8-pin SOIC (Small Outline Integrated Circuit) package with 1.27 mm lead pitch, 3.9 mm body width, and surface-mount compatibility. Pin functions are validated per TI SNAS531B Figure 2 (SOIC top view).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| CS | Chip Select | Active-low enable; must remain low for entire conversion cycle (≥32 μs) |
| CLK | Serial Clock Input | Drives internal timing; supports 10–400 kHz; rising edge clocks DI, falling edge outputs DO |
| DI | Data Input | Accepts start bit + 2-bit MUX address during setup; ignored after conversion begins |
| DO | Data Output | Tri-state serial output; MSB-first by default; LSB-first enabled via SE control |
| VCC | Positive Supply | 4.5–6.3 V power source; also serves as internal reference in ratiometric mode |
| GND | Ground Reference | Analog and digital common return; critical for noise immunity in mixed-signal layouts |
| IN0 | Analog Input Channel 0 | Configurable as single-ended (+) or differential (+) with IN1; voltage range: −0.05 V to VCC + 0.05 V |
| IN1 | Analog Input Channel 1 | Configurable as single-ended (+) or differential (−) with IN0; shares same voltage range and leakage specs |
Key Features
| Feature | Design Value |
|---|---|
| MICROWIRE-compatible serial interface | Direct connection to COPS-family processors without level-shifting or protocol translation |
| Software-configurable 2-channel MUX | Single-ended or true differential input selection per conversion via 3-bit address sequence |
| Ratiometric operation with VCC-referenced conversion | Eliminates need for precision external reference; maintains code accuracy as supply drifts |
| No zero or full-scale adjustment required | Reduces BOM count and production calibration steps; ±1 LSB error guaranteed over temperature |
| Shunt regulator support for high-voltage supplies | Enables direct connection to V+ up to 8.5 V while protecting internal circuitry via internal zener clamp |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 8-bit serial ADC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADC0832CCN/NOPB | Same electrical specs but in 8-pin PDIP package; higher thermal resistance and larger footprint | Suitable for prototyping or through-hole assembly; not recommended for space-constrained PCBs | Select ADC0832CCN/NOPB only when manual soldering or breadboard evaluation is required |
| MCP3002-I/P | 10-bit resolution, SPI interface, 2.7–5.5 V supply, ±1 LSB INL; no internal shunt regulator | Better resolution for precision measurement; lacks V+ shunt capability for high-supply operation | Choose MCP3002-I/P when higher resolution is critical and supply is stable; ADC0832CCWM/NOPB preferred for 5 V ratiometric simplicity |
Compared with ADC0832CCN/NOPB, the ADC0832CCWM/NOPB offers identical functionality in a smaller SOIC-8 package ideal for volume production, while the MCP3002-I/P provides 2 extra bits of resolution at the cost of increased supply sensitivity and no integrated shunt regulation-making ADC0832CCWM/NOPB more robust in cost-driven, supply-variable industrial environments.

FAQ
What is the operating temperature range for ADC0832CCWM/NOPB?
The ADC0832CCWM/NOPB is specified for operation from 0°C to +70°C, matching the CCWM grade designation. This commercial-grade range supports indoor industrial controls, consumer electronics, and non-automotive embedded applications. It does not meet extended or automotive temperature requirements (−40°C to +85°C), which apply to CIWM or BC-grade variants.
Does ADC0832CCWM/NOPB require an external voltage reference?
No, ADC0832CCWM/NOPB does not require an external voltage reference. Its VREF input is internally connected to VCC, enabling ratiometric operation where the full-scale input range tracks the supply voltage. This eliminates external reference components and simplifies design for applications where absolute accuracy is secondary to supply tolerance.
How many analog input channels does ADC0832CCWM/NOPB support?
ADC0832CCWM/NOPB supports two analog input channels (IN0 and IN1), configurable as either single-ended inputs or as a differential pair. Unlike the ADC0834 or ADC0838, it does not support 4- or 8-channel multiplexing. Channel selection and input mode (single-ended/differential) are controlled entirely by the 3-bit software-addressing sequence sent via the DI pin.
Can ADC0832CCWM/NOPB operate from a supply voltage higher than 5 V?
Yes, ADC0832CCWM/NOPB can operate from supplies up to 6.3 V DC on VCC. Additionally, its V+ pin supports connection to voltages up to 8.5 V via the internal shunt regulator, allowing use in systems with higher unregulated rails-provided current into V+ is limited by an external series resistor to avoid exceeding 15 mA absolute maximum rating.
Is ADC0832CCWM/NOPB pin-compatible with other members of the ADC083x family?
No, ADC0832CCWM/NOPB is not pin-compatible with ADC0831, ADC0834, or ADC0838 due to differing pin counts (8-pin SOIC vs. 14- or 20-pin packages) and distinct pin assignments. While functional similarities exist across the family, PCB layout and routing must be specific to the ADC0832CCWM/NOPB's 8-pin SOIC footprint and signal mapping.
