TLV0834IN Übersicht
An ADC converts an analog voltage into a digital value for processing, measurement, or control. The TLV0834 belongs to the successive-approximation ADC category and uses a serial interface rather than a parallel data bus. Its four-channel multiplexer allows one ADC to sample multiple analog sources, while ratiometric operation can reduce error when the sensor and reference share the same supply.
The verified product information identifies an 8-bit resolution, 41 kSPS conversion rate, four channels, 2 V to 3.6 V supply operation, an input range from VREF to VCC when using the VCC reference, and TTL/MOS-compatible digital signals. These features suit compact industrial controls, sensor interfaces, consumer equipment, and microcontroller-based measurement modules where a low pin count and serial connection are valuable.
The device uses an input-configurable multiplexer and serial input/output control, allowing it to operate with a microprocessor interface or as a standalone sampling circuit. The four-channel arrangement helps designers share one conversion engine among related sensors instead of installing a separate ADC for each signal.
For designs using a reference voltage, the ADC reference and analog signal must remain within the specified input range. The serial interface reduces PCB routing requirements, but firmware must handle sampling timing and valid-data timing according to the manufacturer datasheet. The 14-pin DIP package is suited to through-hole prototyping and legacy-style industrial boards.
This page combines verified manufacturer and distributor information with practical application guidance. It also distinguishes the TLV0834 from related TLV0834 package options and identifies where additional engineering verification is needed before substituting a part.
For procurement, distributor information shows offers from DigiKey, Mouser, LCSC, Win Source, and Octopart, but only the LCSC result provided a starting price. Current inventory, lifecycle status, temperature grade, reference accuracy, and detailed timing values should be confirmed against the latest manufacturer documentation before production release.

Typische Anwendungen
TLV0834IN ist geeignet für 6 Anwendungs: Industrial Sensor Measurement, Microcontroller Sensor Interface, Battery-Powered Monitoring, Consumer Control Panel, Portable Instrument, Automated Test and Calibration.
Industrial Sensor Measurement
The TLV0834IN fits low-cost industrial measurement systems that need to monitor several analog sensor outputs. Its four-channel multiplexer reduces the number of separate ADC front ends, while the 41 kSPS rate supports responsive sampling of slowly changing process signals. The 2 V to 3.6 V supply range is suitable for compact 3 V-class control boards, and serial output simplifies connections to a microcontroller. Use shielded analog routing, local supply bypassing, and calibration checks for sensor offsets and supply variation.
Empfohlen
Microcontroller Sensor Interface
The TLV0834IN is appropriate for a microcontroller-based sensor interface when the required resolution is 8 bits and the system needs more than one analog channel. The serial interface reduces data-line count compared with a parallel ADC, and the 41 kSPS rate provides useful acquisition headroom for many temperature, level, and position signals. VCC-referenced or ratiometric operation can simplify inexpensive systems. Firmware must implement the ADC's serial timing and must not assume a throughput higher than the verified 41 kSPS specification.
Empfohlen
Battery-Powered Monitoring
The TLV0834IN can be used in a compact battery-powered monitor when the measured signal range and required accuracy are compatible with an 8-bit result. Its 2 V to 3.6 V operating range supports low-voltage electronics, and the serial interface helps limit PCB wiring in a compact enclosure. Ratiometric operation may be useful when the sensor and ADC reference are tied to the same supply. Designers should verify quiescent current, acquisition behavior, and battery impedance, because those values are not included in the retrieved search data.
Empfohlen
Consumer Control Panel
The TLV0834IN is suitable for consumer equipment requiring several low-resolution analog controls or status inputs, such as a small appliance, instrument panel, or simple configuration interface. Four multiplexed inputs allow buttons, potentiometers, dividers, or sensor outputs to share one converter. Serial data keeps the interface manageable in a small PCB, and the 2 V to 3.6 V supply range aligns with many embedded systems. The 8-bit resolution is best suited to coarse control or status measurement rather than precision analog instrumentation.
Empfohlen
Portable Instrument
The TLV0834IN can support a portable instrument that measures multiple low-voltage analog channels and prioritizes compactness over high resolution. The four-channel input multiplexer and serial output reduce the connector and routing burden, while 41 kSPS is sufficient for many control and status signals. A VCC reference simplifies power design in a battery-operated product, although ratiometric operation may improve tracking when the sensor shares the ADC supply. Validate noise, input bandwidth, and acquisition time from the manufacturer datasheet before specifying the measurement accuracy.
Empfohlen
Automated Test and Calibration
The TLV0834IN is useful in a low-cost automated fixture for checking several analog voltages or control points. Four channels allow the fixture to scan test nodes sequentially, and the serial interface can connect to a test controller without requiring a wide parallel bus. The 8-bit result can classify operating windows, monitor supply rails, or provide coarse feedback in a production fixture. For calibration, record the actual reference and supply conditions because the available verified data does not specify accuracy, INL, DNL, or temperature coefficients.

Wichtigste Unterscheidungsmerkmale
- Four-channel multiplexed input in an 8-bit serial ADC (vs. TLC0834CN)
- Low-voltage 2 V to 3.6 V operating range (vs. TLV0834IP)
- Choice of ratiometric or VCC reference operation (vs. TLV0834CN)
- Serial interface reduces PCB wiring (vs. Parallel-interface ADC alternatives)
Designhinweise
Keep the TLV0834IN supply within the verified 2 V to 3.6 V range and place the supply bypass capacitor close to the device pins. If the design uses VCC-referenced or ratiometric conversion, supply noise and ripple can influence the digital result, so provide a low-impedance supply path and avoid sharing sensitive analog returns with switching-current paths. Verify the exact decoupling recommendation and allowable ripple in the manufacturer datasheet.
Route the serial clock, data, and control traces away from high-current switching nodes and noisy analog inputs. Keep the analog input traces short, use a continuous ground reference, and place any input filtering components close to the ADC. The four-channel multiplexer makes channel-to-channel layout consistency important: similar trace geometry and grounding help reduce channel-dependent error. Exact trace spacing and grounding guidance should follow the package and reference layout in the datasheet.
Do not treat the 41 kSPS figure as the complete system throughput without checking serial timing, acquisition behavior, and controller clocking. Also do not infer the TLV0834IN pinout from the 14-pin DIP footprint: analog inputs, serial signals, supply, reference, and ground assignments must come from the exact datasheet. Verify channel-selection logic and the device's data-valid behavior before writing production firmware.
Compliance-Informationen
