Product details
Overview
ADC0832CCN/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 operation from a single 5 V supply. It serves as a low-power, ratiometric ADC for embedded sensor signal conditioning in industrial monitoring systems.
For engineers reviewing the ADC0832CCN/NOPB datasheet, ADC0832CCN/NOPB pinout, ADC0832CCN/NOPB application, or ADC0832CCN/NOPB equivalent, key selection considerations include its 2-channel differential/single-ended MUX capability, TTL/MOS I/O compatibility, absence of zero/full-scale trim requirements, and suitability for remote analog acquisition over serial digital links.
Technical Context
The ADC0832CCN/NOPB implements a sample-data comparator architecture with a resistor ladder DAC for successive approximation. Its 2-channel multiplexer supports both single-ended and differential input modes via software-controlled address bits shifted in on the DI line prior to conversion.
Conversion begins after MUX settling (½ clock period), with SAR status going high and DO outputting MSB-first data on falling clock edges. The device operates ratiometrically with VREF tied to VCC or with an external reference, and includes internal zener-based shunt regulation enabling operation from higher voltage supplies via the V+ pin.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Resolution | 8 bits - delivers 256 discrete output codes across full-scale range |
| Total Unadjusted Error | ±1 LSB - guarantees monotonicity and no missing codes at room temperature |
| Conversion Time | 32 μs - fixed latency per conversion at 250 kHz clock, enabling up to ~31.25 kSPS throughput |
| Supply Voltage | 4.5 V to 6.3 V - supports direct connection to standard 5 V logic rails with margin |
| Input Range | 0 V to 5 V - compatible with single-supply transducer outputs when VREF = VCC |
| Power Dissipation | 15 mW - enables battery-powered or thermally constrained designs without heatsinking |
| Reference Input | Ratiometric or absolute - VREF may be tied to VCC (internal connection on ADC0832-N) or driven externally for precision scaling |
Pinout & Package
ADC0832CCN/NOPB is housed in an 8-pin plastic DIP (PDIP) package with 0.3-inch width, suitable for through-hole prototyping and industrial PCB layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC | Positive Supply | Primary 5 V power rail; also internally connected to VREF in ratiometric mode |
| GND | Ground Reference | Analog and digital common return; COM pin internally tied to GND |
| CLK | Serial Clock Input | Asynchronous edge-triggered timing source for MUX addressing and data shift-out |
| CS | Chip Select | Active-low enable; must remain low throughout entire conversion cycle |
| DI | Data Input | Serial line for shifting in start bit and 2-bit MUX address before conversion |
| DO | Data Output | Tri-state serial output delivering 8-bit MSB-first result during conversion |
| IN0 | Analog Input Channel 0 | Configurable as single-ended (+) or differential (+) paired with IN1 |

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 |
|---|---|---|---|
| ADC0832CN | Same die, non-NOPB variant with leaded finish; identical electrical specs and pinout | No RoHS compliance; unsuitable for lead-free assembly processes | Select ADC0832CN only for legacy repair or non-RoHS production environments |
| ADS7822U | 12-bit resolution, SPI interface, 2.7–5.25 V supply, 1.25 μs conversion time, higher power (3.5 mW active) | Higher precision required; faster sampling needed; lower supply voltage tolerance critical | Choose ADS7822U when 12-bit resolution and sub-microsecond latency outweigh cost and power trade-offs |
Compared with ADC0832CN, the ADC0832CCN/NOPB provides RoHS-compliant packaging without electrical compromise; compared with ADS7822U, it offers lower cost and simpler interface at the expense of resolution and speed-making it optimal for cost-sensitive 8-bit industrial sensing where 32 μs latency is acceptable.

FAQ
What is the maximum clock frequency supported by ADC0832CCN/NOPB?
The ADC0832CCN/NOPB supports a maximum clock frequency of 400 kHz, as specified in its AC characteristics table. At this rate, conversion time reduces to approximately 20 μs. However, the typical operating clock is 250 kHz, yielding the documented 32 μs conversion time. Exceeding 400 kHz may cause timing violations and invalid output codes.
Does ADC0832CCN/NOPB require external zero or full-scale calibration?
No, ADC0832CCN/NOPB does not require external zero or full-scale adjustment. Its total unadjusted error is guaranteed at ±1 LSB over temperature, and factory trimming ensures monotonic operation across the full 8-bit range. This eliminates production calibration steps and reduces system-level test complexity.
Can ADC0832CCN/NOPB operate with a reference voltage lower than 5 V?
Yes, ADC0832CCN/NOPB can operate with VREF as low as 1.3 kΩ minimum input resistance allows-typically down to ~1.5 V-enabling digitization of sub-5 V transducer spans. However, LSB size scales linearly (e.g., 1 LSB = VREF/256), so reduced VREF increases sensitivity to noise and source impedance errors.
How is differential mode configured on ADC0832CCN/NOPB?
Differential mode on ADC0832CCN/NOPB is selected by shifting a start bit followed by a 2-bit MUX address ('00') into the DI pin before conversion. IN0 becomes the positive input and IN1 the negative input. Polarity reversal is not supported-the ADC0832CCN/NOPB only implements one fixed differential pair orientation.
Is ADC0832CCN/NOPB pin-compatible with ADC0831CCN/NOPB or ADC0834CCN/NOPB?
No, ADC0832CCN/NOPB is not pin-compatible with ADC0831CCN/NOPB (8-pin, single-input) or ADC0834CCN/NOPB (14-pin, 4-channel). While all share the same 8-pin PDIP footprint, ADC0834CCN/NOPB requires additional pins for extra channels and addressing logic. PCB layout must match the specific part's pin count and function mapping.
