Product details
Overview
ADC128S052QCMTX/NOPB from Texas Instruments is a 12-bit, 8-channel successive-approximation (SAR) ADC with 200–500 kSPS throughput, independent analog (VA) and digital (VD) supplies (2.7 V to 5.25 V), SPI-compatible 4-wire serial interface, and integrated track-and-hold. It serves as a precision sensor signal digitizer in automotive navigation and industrial control systems.
For engineers reviewing the ADC128S052QCMTX/NOPB datasheet, ADC128S052QCMTX/NOPB pinout, ADC128S052QCMTX/NOPB application, or ADC128S052QCMTX/NOPB equivalent, key selection criteria include channel count, INL/DNL performance at temperature, power-down current, SPI timing compliance, and TSSOP-16 thermal resistance for embedded deployment.
Technical Context
The ADC128S052QCMTX/NOPB implements a charge-redistribution SAR architecture with internal track-and-hold, enabling full 12-bit resolution without external sample-hold circuitry. Its conversion sequence requires exactly 16 SCLK cycles per sample: 3 cycles in track mode followed by 13 in hold/convert mode.
It supports continuous and burst conversion modes controlled via CS; power state is fully synchronized to chip select-low CS enables normal operation (1.6 mW typical at 3 V), high CS forces shutdown (0.06 µW). Analog input range is 0 V to VA, with VA serving as both supply and reference voltage.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Resolution | 12-bit SAR with no missing codes; delivers 4096 discrete output levels for precise sensor quantization. |
| Sample Rate | 200–500 kSPS; supports real-time monitoring of fast-changing analog signals like motor position or battery voltage. |
| INL / DNL | ±1 LSB max INL, +1.3/−0.9 LSB max DNL at 5 V; ensures monotonicity and linearity critical for closed-loop control. |
| Power Consumption | 1.6 mW typical at 3 V / 500 kSPS; drops to 0.06 µW in shutdown-enables ultra-low-power wake-on-event sensing. |
| Analog/Digital Supplies | VA = 2.7–5.25 V (reference source), VD = 2.7–VA; allows flexible rail partitioning to reduce digital noise coupling into analog path. |
| SPI Compatibility | 4-wire interface (CS, SCLK, DIN, DOUT) compatible with SPI, QSPI, and MICROWIRE; supports 3.2–8 MHz clock for deterministic timing. |
| Operating Temperature | −40°C to +105°C (industrial grade); validated for under-hood automotive and factory-floor environments. |
| Package | 16-pin TSSOP (4.4 mm × 5.0 mm); surface-mount compatible with standard reflow profiles and IPC-7351B land patterns. |
Pinout & Package
ADC128S052QCMTX/NOPB is housed in a 16-pin TSSOP package with exposed pad (PW suffix), optimized for thermal dissipation (RθJA = 110°C/W) and board-level EMI suppression.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, CS | Chip Select Input | Active-low frame initiator: falling edge triggers track mode; rising edge places DOUT in high-impedance state. |
| 2, VA | Analog Supply & Reference | Primary analog rail (2.7–5.25 V); also defines full-scale input range (0 V to VA); requires dual capacitor bypass (1 µF + 0.1 µF). |
| 3, AGND | Analog Ground Return | Reference node for analog inputs and VA; must be routed separately from DGND to minimize noise coupling. |
| 5–12, IN0–IN7 | Single-Ended Analog Inputs | Eight multiplexed channels accepting 0 V to VA; no internal gain or PGA-requires external signal conditioning if needed. |
| 13, VD | Digital Supply | Digital rail (2.7 V to VA); independent biasing prevents digital switching noise from modulating VA reference accuracy. |
| 14, DIN | Serial Data Input | Loads 3-bit channel address (ADD2–ADD0) on first 3 rising SCLK edges after CS fall; MSB-first protocol. |
| 15, DOUT | Serial Data Output | Outputs 12-bit result MSB-first on SCLK falling edges 5–16; tri-stated when CS is high. |
| 16, SCLK | Serial Clock Input | Master clock (3.2–8 MHz); directly controls conversion timing and data transfer; duty cycle 30–70% required. |
Key Features
| Feature | Design Value |
|---|---|
| Independent VA and VD supplies | Enables split-rail design: clean analog reference (VA) isolated from noisy digital domain (VD), improving SNR by >70 dB. |
| Integrated track-and-hold | Eliminates need for external THA; acquisition time fixed at 3 SCLK cycles, simplifying timing budget and PCB layout. |
| Low-power shutdown mode | 0.06 µW consumption at 3 V allows battery-powered systems to sleep between measurements without compromising wake latency. |
| Straight binary output coding | Direct mapping to unsigned integer values (0x000–0xFFF); avoids offset-binary translation overhead in MCU firmware. |
| Channel selection via DIN | Dynamic input routing: next channel address loaded during current conversion, enabling seamless multi-channel scanning. |
| AEC-Q100 Grade-1 qualification | Validated for −40°C to +125°C operation (Q1 variant); ADC128S052QCMTX/NOPB shares same die and TSSOP package. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 8-channel, 12-bit SAR ADC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADS7953SRHBT | 12-bit, 16-channel, 1 MSPS, SPI interface; higher throughput but larger 32-pin QFN package and 3.3-V-only VD supply. | Better suited for high-channel-count data loggers requiring >500 kSPS; less optimal for space-constrained automotive modules. | Select ADS7953SRHBT when channel count >8 or sample rate >500 kSPS is required; verify VD compatibility with system rail architecture. |
| MAX11126ETI+ | 12-bit, 8-channel, 500 kSPS, SPI interface; identical channel count and speed, but uses internal reference and lacks independent VD. | Ideal for cost-sensitive portable instruments where reference stability is less critical than supply simplicity. | Choose MAX11126ETI+ for simplified power design (single 3.3 V rail) and lower component count; accept reduced reference flexibility. |
Compared with ADS7953SRHBT and MAX11126ETI+, ADC128S052QCMTX/NOPB offers unique independent VA/VD rails and TSSOP-16 footprint-critical for noise-sensitive automotive and industrial designs where supply partitioning and thermal management are prioritized over raw speed or integration density.

FAQ
What is the maximum clock frequency supported by ADC128S052QCMTX/NOPB?
The ADC128S052QCMTX/NOPB supports a maximum SCLK frequency of 8 MHz, with minimum clock frequency of 3.2 MHz. This range ensures reliable conversion timing across its full 200–500 kSPS sample rate, and accommodates common microcontroller SPI peripheral limits. Operation outside this range may cause timing violations or incomplete conversions.
Does ADC128S052QCMTX/NOPB require an external reference voltage?
No, ADC128S052QCMTX/NOPB does not require an external reference. Its VA pin serves as both the analog supply and the reference voltage, establishing a full-scale input range of 0 V to VA. This eliminates the need for a separate precision reference IC, reducing system cost and board area.
How many analog input channels does ADC128S052QCMTX/NOPB support?
ADC128S052QCMTX/NOPB supports eight single-ended analog input channels (IN0 through IN7), selectable via a 3-bit address loaded on the DIN pin during each conversion cycle. Channel sequencing is fully software-controllable without hardware reconfiguration.
What is the power consumption of ADC128S052QCMTX/NOPB in shutdown mode?
In shutdown mode (CS high), ADC128S052QCMTX/NOPB consumes just 0.06 µW at 3 V and 0.25 µW at 5 V. This ultra-low quiescent power enables energy harvesting and battery-operated applications to maintain years of standby operation without significant capacity loss.
Is ADC128S052QCMTX/NOPB qualified for automotive applications?
ADC128S052QCMTX/NOPB is the commercial-industrial variant rated for −40°C to +105°C. While it shares the same silicon die and TSSOP package as the AEC-Q100 Grade-1 qualified ADC128S052-Q1, it is not itself automotive-qualified. For automotive use, specify ADC128S052Q1 or ADC128S052Q1RQ1.
