TLV0831IP - 8-Bit 49 kSPS SAR ADC | Texas Instruments
料号： TLV0831IP ✓ 量产中TLV0831IP 概述
An ADC is a data-conversion IC that transforms an analog voltage into a digital code. The TLV0831IP belongs to the successive-approximation ADC category, where an internal converter compares the input against a series of trial thresholds before producing a digital result. The serial interface reduces the number of signal connections required compared with a parallel ADC, making the device useful in compact embedded control and measurement systems.
The main operating characteristics of the TLV0831IP include 8-bit resolution, a 49 kSPS conversion rate, one input channel, a differential input architecture configurable for single-ended use, and a 2.7 V to 3.6 V supply range. Its serial output can communicate with standard shift registers or microprocessors. The device also supports ratiometric operation or operation using the supply voltage as a reference, according to the manufacturer datasheet description.
The TLV0831IP is a single-input converter, so applications requiring simultaneous sampling of multiple channels need additional circuitry or a multiplexed converter. The serial data interface also requires a suitable microcontroller, shift register, or other digital host to receive and interpret the conversion results. The device is packaged in a through-hole PDIP format, which can simplify prototyping and laboratory assembly compared with surface-mount packages.
Typical uses include low-speed sensor acquisition, industrial process monitoring, battery-operated portable instrumentation, temperature and potentiometer measurement, embedded control loops, and simple data logging. In these applications, the 49 kSPS conversion rate is generally more than adequate for many slowly changing analog signals, while the 8-bit result provides 256 possible digital codes.
Designers should verify the input range, reference arrangement, timing, and serial protocol against the manufacturer datasheet before layout. Because the verified web data does not provide exact pin names, pinout details, accuracy figures, input impedance, or power-consumption values, those parameters must be confirmed from the official TLV0831 documentation. The TLV0831IP is best considered for cost-conscious, low-speed conversion rather than precision or high-throughput measurement.
This product page combines the verified manufacturer and distributor descriptions with practical application guidance, comparison criteria, and procurement links. It intentionally distinguishes confirmed specifications from parameters that require datasheet verification so that engineers can evaluate the converter without relying on unverified generic ADC assumptions.

典型应用
TLV0831IP 适用于 6 应用s: Microcontroller Sensor Acquisition, Potentiometer Position Measurement, Industrial Process Monitoring, Battery-Powered Portable Measurement, Temperature and Resistive Sensing, Simple Data Logging and Control.
Microcontroller Sensor Acquisition
The TLV0831IP fits low-speed sensor acquisition when the host controller needs a compact serial ADC rather than a parallel data bus. Its 8-bit resolution provides 256 digital codes, while the 49 kSPS conversion rate is adequate for many temperature, pressure, light, and resistive-sensor outputs that vary gradually. The 2.7 V to 3.6 V supply range also keeps the converter compatible with common low-voltage embedded systems. Place the serial output lines and supply connections according to the manufacturer pinout, and treat the 0 V to VCC input range as the defining analog signal constraint.
推荐
Potentiometer Position Measurement
A TLV0831IP is appropriate for basic potentiometer position sensing because the converter provides single-ended input configuration, 8-bit resolution, and a 49 kSPS sampling rate. The 256-code result gives sufficient granularity for many control-panel positions, menu selectors, and manual actuators without the cost and complexity of a higher-resolution converter. Use a supply-referenced signal within the verified 0 V to VCC range, apply suitable filtering at the input, and account for any divider impedance and source noise when selecting external resistor values.
推荐
Industrial Process Monitoring
The TLV0831IP can be used in industrial process-monitoring equipment when the monitored variable changes relatively slowly and 8-bit resolution is sufficient for threshold indication or basic control. Its single-channel SAR architecture, serial output, and 2.7 V to 3.6 V operating range support compact embedded acquisition. The key design trade-off is that 8-bit quantization creates approximately 256 codes across the usable range, so applications requiring precise process regulation should use a higher-resolution converter. Verify industrial temperature limits and noise performance in the official datasheet.
推荐
Battery-Powered Portable Measurement
The TLV0831IP suits battery-powered portable instruments where the signal is slow, the display or controller only needs moderate numeric resolution, and a serial interface simplifies wiring. Its low-voltage 2.7 V to 3.6 V supply range allows integration with common energy-harvesting and single-cell systems, although actual current consumption is not present in the verified data and must be checked before sizing the battery. A duty-cycled acquisition strategy can reduce energy use, provided the conversion timing and required sampling interval are taken from the manufacturer documentation.
推荐
Temperature and Resistive Sensing
The TLV0831IP can digitize conditioned outputs from resistive sensors when the application requires eight-bit measurement resolution and periodic sampling rather than continuous high-rate acquisition. The serial output works with shift registers or microprocessors, and the converter may operate ratiometrically with the supply or use VCC as a reference according to the manufacturer description. Ratiometric operation can reduce sensitivity to supply variation when the sensor and reference share the same supply, but sensor excitation, linearity, and error-budget calculations must be validated independently.
推荐
Simple Data Logging and Control
The TLV0831IP is suitable for compact data-logging or supervisory-control modules where a microcontroller periodically requests a conversion and stores the resulting byte. The 49 kSPS maximum rate allows substantially more sampling speed than many slow control variables require, while the serial interface keeps the converter pin count low in an 8-pin PDIP package. Designers should define the sampling interval, averaging strategy, and overflow handling in firmware. If the signal is noisy or the application needs calibrated absolute accuracy, add suitable filtering and use the official accuracy and reference specifications.

设计说明
Do not treat a related TI orderable MPN as automatically interchangeable without checking the official pinout and timing tables. TLV0831IP and TLC0831IP share the confirmed 8-bit, 49 kSPS, single-channel, serial-output concept, but the supplied search snippets do not establish every electrical limit or reference configuration. Before approving a replacement, compare supply voltage, absolute maximum ratings, conversion timing, clock behavior, input range, and digital output timing.
Keep the analog input path short and place any required filtering close to the TLV0831IP input pin. The verified input range is 0 V to VCC, so the source and front end must not exceed that range under transient or fault conditions. If the source impedance is high, verify settling behavior and acquisition time in the manufacturer datasheet; otherwise the 49 kSPS conversion-rate headline should not be interpreted as a guarantee of full-resolution accuracy for every source impedance.
The TLV0831IP uses an 8-pin PDIP package, which favors prototyping and through-hole assembly. Keep the serial clock, data, and control traces away from the analog input and reference routing to reduce coupling. Provide local supply bypassing close to the device and maintain a quiet return path; exact capacitor values and layout guidance should be selected from the manufacturer application information and the final reference configuration.
合规信息
The supplied verified snippets identify an industrial-grade part but do not explicitly state RoHS, REACH, AEC-Q100, lead-free, halogen-free, or conflict-minerals status. AEC-Q100 is marked not_applicable because no automotive qualification claim appears in the verified data.
