TLV0832IP - 8-Bit 44.7 kSPS Serial ADC | Texas Instruments
部品番号: TLV0832IP ✓ 生産中TLV0832IP 概要
An ADC is a data-conversion IC that transforms an analog voltage into a digital code for processing by a microcontroller, comparator, display, or control system. The TLV0832 belongs to the successive-approximation ADC family, whose internal sampling architecture is appropriate for relatively compact, cost-conscious converters that do not require continuous conversion while an input is being measured.
The TLV0832IP provides 8-bit resolution, two analog input pins that can be selected through the serial interface, and a conversion throughput of 44.7 kSPS. Its serial interface supports easy microprocessor interfacing or standalone operation. The input range extends from VSS to VCC, while ratiometric operation allows the converter reference to track the supply when the sensor and ADC share the same reference.
The device uses a successive-approximation conversion process. During each conversion, the internal converter compares the sampled input against a generated reference to determine successive bits of the 8-bit result. Serial control reduces the number of interface pins, leaving the package primarily for power, analog input, and serial communication functions.
Typical uses include industrial sensor acquisition, temperature measurement, battery monitoring, potentiometer and divider readings, and low-cost embedded data logging. For battery-powered systems, the 3 V supply operation and ratiometric measurement can simplify analog front-end design, although application-specific current consumption must be verified from the manufacturer datasheet.
When using the TLV0832IP, connect unused analog inputs appropriately, preserve the required supply and reference arrangement, and account for acquisition time when multiplexed channels are switched. The serial interface timing and command definitions should be taken directly from the manufacturer datasheet rather than inferred from generic ADC conventions.
This page consolidates the verified manufacturer and distributor information for TLV0832IP and provides practical engineering guidance for design decisions. It also distinguishes verified production data from parameters that still require confirmation from the manufacturer datasheet, avoiding unsupported electrical or lifecycle assumptions.

主な用途
TLV0832IP の用途: 6 件s: Industrial Sensor Acquisition, Temperature Monitoring, Battery Voltage Monitoring, Potentiometer Position Sensing, Data Logging and Instrumentation, Embedded Control Systems.
Industrial Sensor Acquisition
The TLV0832IP fits industrial sensor acquisition when the system needs an 8-bit measurement rather than higher-resolution conversion. Its two multiplexed analog inputs can monitor two sensor channels through one converter, while the 44.7 kSPS throughput provides faster sampling than many slow-resolution display-oriented converters. The serial interface also reduces the number of connections required to a controller. Because the supplied information does not include a specific noise figure, common-mode rejection, or acquisition-time value, those parameters should be verified from the manufacturer datasheet before choosing input filtering and sampling intervals.
Temperature Monitoring
The TLV0832IP can digitize a thermistor or resistive temperature sensor in a compact controller when 8-bit resolution is adequate for the required temperature range. Two multiplexed inputs allow a sensor to be paired with a reference channel for calibration, while the 44.7 kSPS rate is substantially higher than the update rate of many temperature systems. A practical design should use ratiometric operation only when the sensor and converter share a stable excitation reference. Pull-up resistance, self-heating error, input filtering, and the resulting temperature resolution remain application-specific and require calculation.
Battery Voltage Monitoring
The TLV0832IP is suitable for monitoring a battery voltage in a compact embedded supply because it accepts an input range extending from VSS to VCC and uses a 3 V nominal supply architecture. A scaled divider can present the battery voltage to one of the two analog inputs, while the second input can remain available for another measurement. The converter’s 8-bit resolution defines the measurement granularity, so divider scaling should preserve usable code range without exceeding the input limits. Actual accuracy depends on resistor tolerance, reference behavior, ADC error, and layout, none of which should be inferred solely from the family-level data.
Potentiometer Position Sensing
The TLV0832IP can convert a potentiometer or resistive divider position in equipment requiring basic level, angle, or travel feedback. Its single-ended input support simplifies the analog connection, while the serial output can be read by a microcontroller without requiring a parallel ADC bus. The 44.7 kSPS conversion rate permits responsive updates during movement, provided the controller and interface support that throughput. Potentiometer wiper noise, dead-band behavior, excitation stability, and the required resolution should be considered together. The verified 8-bit output offers 256 code levels, but usable mechanical accuracy may be lower because of circuit and sensor tolerances.
Data Logging and Instrumentation
The TLV0832IP provides a straightforward serial conversion channel for compact data loggers that record slowly changing analog measurements such as enclosure temperature, supply status, or equipment condition. Its two multiplexed inputs can reduce the number of converter packages, and the 44.7 kSPS maximum rate provides ample headroom for typical logging intervals. Serial control also makes the ADC suitable for a microcontroller with a general-purpose serial peripheral. Designers should define acquisition timing around the actual sample rate rather than treating 44.7 kSPS as mandatory. Input settling time, source impedance, grounding, and protection-network capacitance must be checked against the family datasheet.
Embedded Control Systems
The TLV0832IP works as an input peripheral for embedded control systems that monitor analog thresholds or slowly changing process variables. Two multiplexed channels can represent a sensor and a setpoint or reference, while the 8-bit code can be compared directly or stored by the controller. Its serial interface supports both microprocessor interfacing and standalone operation as identified in the verified TLV0832 family information. For an industrial controller, the designer should confirm noise immunity, reference behavior, and available operating-temperature limits, because those details are not included in the supplied distributor excerpts and should come directly from the current manufacturer documentation.

主な差別化要因
- Two multiplexed inputs in an 8-pin PDIP （vs TLV0831IP)
- Current TLV family positioning with 44.7 kSPS throughput （vs TLC0832IP)
- Single-ended and differential operating options （vs TLV0831IP)
設計ノート
Keep analog input traces short, connect the converter's ground and supply pins as shown in the manufacturer application diagram, and place input and bypass capacitors close to their associated pins. When switching between the two multiplexed inputs, allow the source and input network to settle before starting the next conversion. The supplied excerpts do not include acquisition-time or input-capacitance limits, so those values must be obtained from the current TLV0832 datasheet before setting the conversion interval.
Do not substitute TLV0832IP solely because another member is also an 8-bit serial ADC. Compare the exact PDIP-8 pin table, input-channel assignment, differential-input capability, supply limits, timing, and temperature grade. TLV0831IP has one input rather than two, while TLC0832IP and TLC0832CP require separate datasheet review. Unused or repurposed pins can prevent startup, disturb the serial interface, or place an out-of-range voltage on an input.
Decouple the 3 V supply close to the device and route the return current without sharing narrow paths with analog signals. If the ADC is powered from a regulated rail shared with a switching converter, verify ripple at the ADC pins and preserve the supply operating range specified by the manufacturer. Ratiometric operation can improve tracking when the sensor and ADC share the same reference, but it does not remove ADC offset, gain, and noise errors.
