Product details
Overview
TLV0832IP from Texas Instruments is an 8-bit successive-approximation analog-to-digital converter (ADC) with software-configurable dual-channel multiplexer supporting single-ended or differential inputs. It operates from 2.7 V to 3.6 V, achieves ±1 LSB total unadjusted error, delivers 32 µs conversion time at 250 kHz clock, and interfaces via serial DO/DI lines compatible with TTL/MOS logic - used in industrial sensor signal conditioning where ratiometric accuracy and low-voltage operation are critical.
For engineers reviewing the TLV0832IP datasheet, TLV0832IP pinout, TLV0832IP application, or TLV0832IP equivalent, this page provides verified technical context, validated pin functions, confirmed operating parameters across −40°C to 85°C, and two functionally comparable alternatives for embedded data acquisition systems requiring compact serial ADCs with multiplexed analog inputs.
Technical Context
The TLV0832IP implements a sample-data-comparator SAR architecture with internal resistive ladder and comparator. Its multiplexer is controlled via serial DI input using a 3-bit address sequence (start bit + 2-bit assignment), enabling dynamic selection of CH0/CH1 and SGL/DIF mode with polarity assignment - unlike the fixed-input TLV0831.
Conversion begins on CS low assertion and completes in exactly eight clock periods; MSB-first data appears on DO during conversion, followed by LSB-first data post-conversion. Ratiometric operation is supported by tying REF to VCC (internally connected), and common-mode rejection is enabled in differential mode with full-scale input range of 0 V to VCC.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Resolution | 8-bit - delivers 256 discrete digital codes for analog input quantization. |
| Supply Voltage Range | 2.7 V to 3.6 V - enables direct interface with 3.3 V microcontrollers and battery-powered systems. |
| Total Unadjusted Error | ±1 LSB - includes offset, full-scale, linearity, and multiplexer errors; no calibration required for basic accuracy. |
| Conversion Time | 32 µs at fCLK = 250 kHz - fixed 8-clock-cycle timing ensures deterministic latency for real-time sampling. |
| Input Configuration | Software-selectable twin-channel (CH0/CH1) with single-ended or differential mode - supports common-mode rejection and flexible sensor interfacing. |
| Operating Temperature | −40°C to +85°C - qualified for industrial environments without derating. |
| Digital Interface | 3-wire serial (CS, CLK, DO/DI) - enables bidirectional single-wire communication using processor I/O bit. |
Pinout & Package
TLV0832IP is housed in an 8-pin plastic DIP (PDIP) package with 0.3-inch body width and through-hole mounting. Pin 1 is identified by a notch or dot; leads are tin-lead (NIPDAU) finished per TI's production specification.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (CS) | Chip Select Input | Active-low enable: must remain low for entire conversion; initiates internal logic and multiplexer settling. |
| 2 (CH0) | Analog Input Channel 0 | Configurable as positive or negative input in differential mode; single-ended input when CH1 grounded. |
| 3 (CH1) | Analog Input Channel 1 | Paired with CH0 for differential measurement; polarity assignable via DI address sequence. |
| 4 (GND) | Analog/Digital Ground | Common reference for analog inputs, digital logic, and internal circuitry - requires low-impedance connection. |
| 5 (VCC/REF) | Supply & Reference Voltage | Single pin serves both VCC (2.7–3.6 V) and internal reference; enables ratiometric conversion when tied to sensor supply. |
| 6 (CLK) | Serial Clock Input | Controls timing of DI address loading and DO data output; supports 250 kHz (min) to 600 kHz (max) at 3.3 V. |
| 7 (DO) | Serial Data Output | Tri-state output: MSB-first during conversion, LSB-first after completion; high-impedance when CS high. |
| 8 (DI) | Serial Data Input | Accepts 3-bit multiplexer address (start + SGL/DIF + ODD/EVEN); disabled during conversion to prevent interference. |
Key Features
| Feature | Design Value |
|---|---|
| Software-Configurable MUX | Dynamic channel and input mode selection via serial DI - eliminates external switches or jumpers in multi-sensor designs. |
| Differential Input Support | Enables common-mode noise rejection and offset cancellation - critical for thermocouple or bridge sensor interfaces. |
| Ratiometric Operation | VCC used as reference eliminates need for precision external reference; maintains accuracy proportional to sensor excitation voltage. |
| Low-Power Serial Interface | 3-wire protocol with bidirectional DO/DI capability reduces PCB routing and MCU pin count versus parallel ADCs. |
| Industrial Temperature Range | −40°C to +85°C operation without performance degradation - suitable for factory automation and motor control systems. |

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 |
|---|---|---|---|
| TLV0832CD | Same core architecture and pinout, but SOIC-8 package and 0°C to 70°C rating. | Suitable for commercial-grade PCBs with surface-mount assembly; lacks extended temperature qualification. | Select TLV0832CD for cost-sensitive consumer electronics where industrial temp range is unnecessary. |
| ADC0832CCN | National Semiconductor legacy part; functionally equivalent at 3 V, but higher ICC (3.5 mA typical) and no −40°C support. | Legacy replacement only; not recommended for new designs due to obsolescence and higher power draw. | Choose TLV0832IP over ADC0832CCN when long-term supply continuity, lower power, or extended temperature operation is required. |
Compared with TLV0832CD and ADC0832CCN, the TLV0832IP uniquely combines PDIP packaging for prototyping and repairability, −40°C to +85°C qualification for harsh environments, and 1.5–2.5 mA supply current - making it optimal for industrial field instruments and medical devices needing through-hole reliability and wide thermal margin.

FAQ
What is the maximum clock frequency supported by TLV0832IP?
The TLV0832IP supports up to 600 kHz clock frequency when operated at VCC = 3.3 V, as specified in the recommended operating conditions. At 2.7 V supply, the maximum clock frequency is limited to 250 kHz. Exceeding these limits may cause conversion errors or timing violations, particularly in the multiplexer-addressing and data-output phases.
Does TLV0832IP require an external reference voltage?
No, the TLV0832IP does not require an external reference voltage. Its VCC/REF pin serves as both supply and internal reference; ratiometric operation is achieved by connecting the analog sensor's excitation source directly to VCC/REF. This eliminates external reference components and simplifies design for systems where accuracy scales with supply stability.
How is differential mode configured on TLV0832IP?
Differential mode on TLV0832IP is configured via the 2-bit assignment word sent on the DI pin during the multiplexer-addressing sequence: '10' selects differential mode with CH0 as positive and CH1 as negative input. Polarity can be reversed by selecting '11', assigning CH1 as positive. The start bit must precede this word, and CS must remain low throughout addressing.
What is the meaning of "Total Unadjusted Error = ±1 LSB" for TLV0832IP?
This specification means the combined worst-case deviation - including offset, full-scale, integral nonlinearity, and multiplexer switching errors - is bounded within ±1 least-significant bit across the full operating temperature and supply range. No calibration is needed to meet this accuracy, making TLV0832IP suitable for cost-sensitive applications where trimming is impractical.
Can TLV0832IP operate with a 2.5 V supply?
No, TLV0832IP is not rated for 2.5 V operation. Its absolute minimum supply voltage is 2.7 V per the recommended operating conditions, and operation below this level risks incomplete internal logic states, increased conversion error, or failure to initiate conversion. For 2.5 V systems, consider newer TI ADCs such as ADS7822 or ADS7828.
