Product details
Overview
ADC0848BCV/NOPB from Texas Instruments is an 8-bit CMOS successive-approximation analog-to-digital converter with an integrated 8-channel analog multiplexer, ratiometric operation capability, ±½ LSB total unadjusted error at VREF = 5.00 VDC, and 40 μs conversion time. It operates from a single 5 V supply and supports differential, pseudo-differential, and single-ended input configurations for industrial data acquisition systems.
For engineers reviewing the ADC0848BCV/NOPB datasheet, ADC0848BCV/NOPB pinout, ADC0848BCV/NOPB application, or ADC0848BCV/NOPB equivalent, key selection considerations include its 8-channel software-configurable MUX, internal clock, TRI-STATE output latches for direct microprocessor bus interfacing, and −40°C to +85°C operating temperature range.
Technical Context
The ADC0848BCV/NOPB implements a sampled-data comparator architecture enabling true differential analog input conversion via successive approximation. Its 8-channel MUX is controlled by five address inputs (MA0–MA4), supporting three distinct input modes-differential (e.g., CH1/CH2), pseudo-differential (e.g., CH1–CH3 referenced to CH4), and single-ended-with mode selection determined by latch configuration during WR strobe.
Conversion is initiated by CS and WR signals; the internal clock sets tC ≤ 40 μs. Output data appears on DB0–DB7 after conversion completion, with INTR asserted low and latched data held until RD strobe clears INTR and enables readout. The device requires no zero or full-scale adjustment and accepts reference voltages up to VCC.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Resolution | 8 bits - delivers 256 discrete digital codes over full-scale input range |
| Total Unadjusted Error | ±½ LSB (tested) at VREF = 5.00 VDC - defines worst-case deviation from ideal transfer curve without calibration |
| Conversion Time | 40 μs maximum - determines minimum sampling period and system throughput in real-time acquisition |
| Supply Voltage | 4.5 VDC to 6.0 VDC - supports standard 5 V logic rails with ±5% tolerance margin |
| Input Range | 0 V to 5 V with single 5 V supply - enables direct interface to sensors and transducers without level-shifting |
| Operating Temperature | −40°C to +85°C - qualified for industrial environments including factory automation and motor control |
| Power Dissipation | 15 mW typical - allows integration into power-constrained embedded systems without active cooling |
Pinout & Package
ADC0848BCV/NOPB is housed in a 28-pin PLCC (Plastic Leaded Chip Carrier) package with gull-wing leads, designed for surface-mount assembly and compatible with JEDEC MS-026 standards. The package provides mechanical robustness and thermal performance suitable for industrial PCB layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| DB0–DB7 | Digital output data bus | TRI-STATE latched outputs directly drive microprocessor data bus; high-impedance when CS or RD inactive |
| CS | Chip select input | Active-low enable for all internal functions; must be low during WR or RD operations |
| WR | Write strobe input | Falling edge resets INTR; rising edge with RD high loads MUX address and starts conversion |
| RD | Read strobe input | Active-low signal that outputs conversion result and clears INTR when CS is low |
| INTR | Interrupt output | Open-drain active-low flag indicating conversion completion; requires external pull-up |
| VREF | Analog reference input | Sets full-scale voltage span (VIN(MAX) − VIN(MIN)); supports ratiometric or absolute referencing |
| AGND | Analog ground | Reference node for analog inputs and internal circuitry; must be separated from DGND for noise immunity |
| DGND | Digital ground | Return path for digital I/O and logic circuits; separation from AGND minimizes digital switching noise coupling |
| MA0–MA4 | Multiplexer address inputs | Shared with DB0–DB4; latched on rising WR edge to select one of eight analog channels or input mode |
| CH1–CH8 | Analog input channels | Eight single-ended inputs configurable as four differential pairs or pseudo-differential groups |
Key Features
| Feature | Design Value |
|---|---|
| Software-configurable 8-channel MUX | Enables flexible analog routing without external switches-reduces BOM count and layout complexity in multi-sensor systems |
| Differential input mode | Provides low-frequency common-mode rejection (e.g., 60 Hz noise) by sampling "+" and "−" inputs within ½ clock period |
| Ratiometric operation support | Allows VREF tied to VCC, eliminating need for precision reference and relaxing supply stability requirements in sensor interfaces |
| No zero or full-scale adjustment required | Reduces production calibration steps and field maintenance-enables plug-and-play deployment in OEM instrumentation |
| TRI-STATE output latches | Permits direct connection to shared microprocessor data buses without glue logic or bus transceivers |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 8-bit successive-approximation ADC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADC0844CCN/NOPB | 4-channel MUX only; same 8-bit resolution, ±1 LSB error spec, and 40 μs conversion time but lacks CH5–CH8 | Restricted to ≤4 analog inputs; suitable for cost-sensitive designs where channel count is not limiting | Select when system requires only four analog sources and board space or BOM cost optimization is critical |
| MAX187ACPP+ | Serial SPI interface (vs. parallel); 8-bit resolution; 12 μs conversion time; requires external reference and clock | Reduces pin count and PCB routing complexity but increases firmware dependency and interrupt latency | Prefer for new designs prioritizing minimal I/O usage and higher speed, provided SPI host support exists |

FAQ
What is the operating temperature range of the ADC0848BCV/NOPB?
The ADC0848BCV/NOPB is rated for operation from −40°C to +85°C, making it suitable for industrial environments such as factory floor controllers, motor drives, and outdoor sensor nodes. This rating is confirmed in the SNAS523D datasheet under Operating Conditions for part number ADC0848BCV, and applies directly to ADC0848BCV/NOPB as the NOPB suffix denotes lead-free packaging without functional change.
Does the ADC0848BCV/NOPB require an external clock source?
No, the ADC0848BCV/NOPB includes an internal clock generator and does not require an external clock. Conversion timing is fully self-contained, with a maximum conversion time of 40 μs defined by the internal oscillator. This simplifies system design by eliminating clock routing, jitter concerns, and external component dependencies for the ADC0848BCV/NOPB.
Can the ADC0848BCV/NOPB perform differential measurements?
Yes, the ADC0848BCV/NOPB supports true differential input mode-for example, CH1 as VIN(+) and CH2 as VIN(−)-with common-mode rejection optimized for low-frequency noise like 60 Hz. Table 2 in the SNAS523D datasheet explicitly defines differential addressing for ADC0848BCV/NOPB, and the functional block diagram confirms differential comparator architecture within the ADC0848BCV/NOPB.
What package type is used for the ADC0848BCV/NOPB?
The ADC0848BCV/NOPB uses a 28-pin PLCC (Plastic Leaded Chip Carrier) package, identified as "PLCC (FN)" in TI's packaging addendum. This surface-mount package features gull-wing leads, conforms to JEDEC MS-026, and is distinct from the PDIP variants used for other members of the ADC084x family. The marking "ADC0848 BCV" appears on the top of the ADC0848BCV/NOPB package.
Is the ADC0848BCV/NOPB pin-compatible with the ADC0844 series?
No, the ADC0848BCV/NOPB is not pin-compatible with the ADC0844 series. While both share functional similarities, the ADC0848BCV/NOPB uses a 28-pin PLCC package with five MUX address lines (MA0–MA4), whereas the ADC0844CCN/NOPB uses a 20-pin PDIP with only four address lines (MA0–MA3). Pin counts, layouts, and signal assignments differ fundamentally between ADC0848BCV/NOPB and ADC0844 devices.
