Product details
Overview
ADC08832IMM/NOPB from Texas Instruments is an 8-bit successive-approximation analog-to-digital converter with integrated 2-channel analog multiplexer, track/hold circuitry, and 3-wire serial interface (CS, CLK, DI/DO). It operates from a single 5V supply, achieves ≤4μs conversion time at 2MHz clock, and delivers ±1LSB total unadjusted error across −40°C to +85°C. It is used in embedded sensor digitization where low pin count and noise-immune serial data transmission are critical.
For engineers reviewing the ADC08832IMM/NOPB datasheet, ADC08832IMM/NOPB pinout, ADC08832IMM/NOPB application, or ADC08832IMM/NOPB equivalent, key selection considerations include its software-configurable single-ended/differential input modes, VREF-tied-to-VCC architecture, 153ksps sampling rate, and SOIC/VSSOP-8 package compatibility with space-constrained industrial monitoring systems.
Technical Context
The ADC08832IMM/NOPB implements a successive-approximation register (SAR) core with built-in sample-and-hold and a configurable 2-channel analog multiplexer. Its internal reference is fixed to VCC, eliminating external reference components and simplifying ratiometric designs. The 3-wire serial interface complies with MICROWIRE protocol, supporting MSB-first output only and requiring no LSB-first configuration.
Conversion is initiated by CS low, followed by a 3-bit MUX address shift-in via DI (start bit + SGL/DIF + ODD/SIGN), then automatic ½-clock settling before SAR operation. Analog inputs tolerate −0.05V to VCC+0.05V, enabled by on-chip clamping diodes, and support single-ended, differential, or pseudo-differential configurations per software command.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Resolution | 8 bits - delivers 256 discrete digital codes for full-scale analog input range |
| Conversion Time | 4 μs max at 2 MHz clock - enables up to 153 ksps sampling rate for real-time waveform capture |
| Total Unadjusted Error | ±1 LSB - guarantees monotonicity and no missing codes over full temperature range |
| Supply Voltage | 4.5 V to 6.0 V - supports standard 5V systems with ±10% tolerance without regulation |

Pinout & Package
ADC08832IMM/NOPB is housed in an 8-pin VSSOP (DGK) package - 3.0 mm × 3.0 mm, 0.65 mm pitch - optimized for high-density PCB layouts. Pin functions are validated per TI SNAS015C Rev. MARCH 2013 datasheet Figure 2 and Functional Block Diagram.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (VCC) | Positive supply | Provides power and serves as internal voltage reference source (VREF = VCC) |
| 2 (GND) | Ground reference | Analog and digital common return; requires low-impedance connection to analog ground plane |

| 4 (CLK) | Serial clock input | Drives internal timing; supports 10 kHz–2 MHz; duty cycle 40–60% required for reliable operation |
| 5 (CS) | Chip select | Active-low enable; must remain low throughout conversion; controls entry into low-power mode when high |
| 6 (IN0) | Analog input channel 0 | Configurable as positive or negative input in differential mode; or single-ended input referenced to GND |
| 7 (IN1) | Analog input channel 1 | Paired with IN0 for differential operation; supports polarity reversal via MUX address bits |
| 8 (DO) | Serial data output | Tri-state output; delivers 8-bit MSB-first conversion result after MUX settling; high-impedance when CS high |
Key Features
| Feature | Design Value |

| 3-wire MICROWIRE-compatible serial interface | Reduces host microcontroller I/O usage to three pins (CS, CLK, DI/DO) and supports daisy-chaining in multi-converter systems |
| No zero or full-scale adjustment required | Guarantees factory-calibrated accuracy; removes production calibration step and associated test fixtures |
Applications
| Remote Sensor Digitization | Industrial Process Monitoring |
|---|---|
|
Use Scenario: Converting thermistor, RTD, or pressure transducer outputs located meters away from the controller in noisy factory environments.

IC Role / Device Role / Timing Role: ADC08832IMM/NOPB serves as dual-channel acquisition engine, enabling sequential scanning of two sensors per conversion cycle using software-defined MUX addressing. Use Value: Reduces component count versus discrete ADC + MUX solutions; 8-pin VSSOP footprint fits high-channel-density modular I/O designs. |
| Embedded System Telemetry | Noise-Resilient Instrumentation |
|
Use Scenario: Battery-powered environmental data loggers acquiring voltage outputs from gas sensors, humidity ICs, and light detectors.

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 | Legacy 8-bit serial ADC; no internal track/hold; requires external sample-hold or careful timing control | Lacks integrated track/hold and multiplexer flexibility; limited to fixed single-ended inputs | Choose only if legacy design reuse is required and external hold circuitry already exists |
| MCP3002-I/P | 10-bit resolution; SPI-compatible interface; separate VREF pin; no internal VREF tie to VCC | Higher resolution but requires external reference; lacks differential polarity reversal capability | Select when absolute accuracy >8-bit and external precision reference is available |
Compared with ADC0832CCN/NOPB, ADC08832IMM/NOPB adds integrated track/hold and software-selectable differential polarity, reducing external components and improving noise immunity. Against MCP3002-I/P, it trades 2-bit resolution for lower system cost, simpler power design, and deterministic 153ksps throughput in VCC-referenced systems.

FAQ
What is the maximum clock frequency supported by ADC08832IMM/NOPB?
The ADC08832IMM/NOPB supports a maximum clock frequency of 2 MHz, as specified in the Electrical Characteristics table under Operating Ratings. At this frequency, conversion time is guaranteed ≤4 μs, enabling a maximum sampling rate of 153 ksps. Operation above 2 MHz may cause timing violations and invalid output codes.
Does ADC08832IMM/NOPB require an external voltage reference?
No, ADC08832IMM/NOPB does not require an external voltage reference. Its reference input is internally tied to VCC, making it inherently ratiometric. This architecture eliminates the need for external reference ICs or resistor dividers, simplifying design and reducing BOM cost compared to variants like ADC08831 that expose a dedicated VREF pin.
Can ADC08832IMM/NOPB perform true differential measurements?
Yes, ADC08832IMM/NOPB supports true differential measurements via its programmable 2-channel multiplexer. Using the MUX address bits, users can configure IN0 as positive and IN1 as negative input-or vice versa-enabling polarity-reversible differential acquisition. This capability rejects common-mode noise and supports transducer bridge readouts without external op-amps.
What package type is used for ADC08832IMM/NOPB?
ADC08832IMM/NOPB is packaged in an 8-pin VSSOP (DGK) package: 3.0 mm × 3.0 mm body, 0.65 mm lead pitch. This ultra-small outline package is surface-mount compatible and optimized for high-density PCB layouts in space-constrained applications such as handheld instruments and modular I/O systems.
How does ADC08832IMM/NOPB enter low-power mode?
ADC08832IMM/NOPB automatically enters low-power mode when the CS (chip select) pin is driven high. In this state, analog circuitry and digital logic transition to static current modes, reducing typical power dissipation to 3.0 mW. The DO pin enters tri-state, and the internal reference ladder continues drawing current-unlike ADC08831, which allows full reference shutdown.
