Product details
Overview
ADC124S051CIMMX/NOPB from Texas Instruments is a 12-bit, 4-channel successive-approximation ADC with serial SPI-compatible interface, operating at 200–500 ksps sample rates over −40°C to +85°C. It features ±0.5 LSB INL (typ), 72.5 dB SNR (typ), and 3.0 mW power consumption at 3V - used in portable instrumentation for multi-sensor analog signal digitization.
For engineers reviewing the ADC124S051CIMMX/NOPB datasheet, ADC124S051CIMMX/NOPB pinout, ADC124S051CIMMX/NOPB application, or ADC124S051CIMMX/NOPB equivalent, this page delivers verified electrical specs, industrial-grade timing behavior, VSSOP-10 package layout, and real-world channel-selection control logic - all confirmed against TI's SNAS260E datasheet.
Technical Context
The ADC124S051CIMMX/NOPB implements a charge-redistribution DAC architecture with internal track-and-hold, supporting four single-ended analog inputs (IN1–IN4) multiplexed via a 3-bit address register loaded on DIN. Conversion begins on CS falling edge and completes in 13 SCLK cycles, with data output MSB-first on DOUT starting at the 5th SCLK falling edge.
It operates across 2.7V–5.25V supply range, uses straight-binary coding, and supports SPI/QSPI/MICROWIRE protocols. Power-down mode reduces current to 38 nA (3.6V) or 60 nA (5.25V), enabling low-duty-cycle remote sensing applications without external shutdown circuitry.
Key Specifications

Pinout & Package
ADC124S051CIMMX/NOPB is housed in a 10-lead VSSOP (Package Code DGS), 3.0 mm × 3.0 mm, 0.5 mm pitch, thermally enhanced package with exposed pad (not electrically connected). Pin 1 is CS; pin 2 is VA; pin 3 is GND; pins 4–7 are IN1–IN4; pin 8 is DIN; pin 9 is DOUT; pin 10 is SCLK.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| CS (Pin 1) | Chip Select Input | Falling edge initiates conversion frame; high state enables power-down mode (38–60 nA). |
| VA (Pin 2) | Analog Supply | Single 2.7–5.25V rail serving as reference and supply; requires 1 µF + 0.1 µF local bypassing. |
| GND (Pin 3) | Analog Ground | Common return for analog inputs and supply; must be star-connected to minimize noise coupling. |
| IN1–IN4 (Pins 4–7) | Analog Inputs | Single-ended, 0V to VA range; input capacitance 33 pF (track) / 3 pF (hold) affects anti-alias filter design. |
| DIN (Pin 8) | Serial Data Input | Loads 3-bit channel address (ADD2:ADD0) on rising SCLK edges during first 8 clocks of each frame. |
| DOUT (Pin 9) | Serial Data Output | Outputs 12-bit result MSB-first on falling SCLK edges; tri-state when CS high. |
| SCLK (Pin 10) | Serial Clock Input | Drives conversion timing and data transfer; supports 50 kHz–16 MHz; duty cycle 30–70%. |
Key Features
| Feature | Design Value |
|---|---|
| Four-channel multiplexed input | Reduces BOM count and PCB area vs. discrete ADCs; supports sequential sampling of sensors or transducers. |
| Full-rate specification (200–500 ksps) | Eliminates interpolation uncertainty - performance validated at every rate within range, not just endpoints. |
| Low-power shutdown mode | 0.14 µW (3.6V) / 0.32 µW (5.25V) enables ultra-low-duty-cycle wake-up architectures in IoT nodes. |
| SPI-compatible serial interface | Direct connection to MSP430, STM32, or C2000 DSPs without protocol translation or glue logic. |
| Internal track-and-hold | Removes need for external sample-hold amplifier; acquisition time fixed at 3 SCLK cycles regardless of input frequency. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 12-bit SAR ADC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADC124S021 | Same pinout and interface, but rated for 50–200 ksps only; lower max clock (8 MHz vs. 16 MHz); 69 dB SNR. | Better suited for low-speed sensor polling where power is less critical than cost. | Select ADC124S021 only if sample rate ≤200 ksps and SNR ≥69 dB suffices. |
| ADC122S101 | 2-channel, 1 Msps capable; higher power (15 mW at 5V); same VSSOP-10 package; SPI-compatible. | Preferred for dual high-speed channels (e.g., current/voltage simultaneous capture) with tighter timing budgets. | Choose ADC122S101 when two independent 1-Msps streams are required and 4-channel mux is unnecessary. |
Compared with ADC124S021 and ADC122S101, the ADC124S051CIMMX/NOPB uniquely balances 4-channel integration, 500-ksps throughput, and sub-3.5-mW 3V operation - making it optimal for space-constrained, battery-aware industrial data acquisition where channel count and mid-range speed are primary constraints.

FAQ
What is the maximum clock frequency supported by ADC124S051CIMMX/NOPB?
The ADC124S051CIMMX/NOPB supports a maximum SCLK frequency of 16 MHz, as specified in its Absolute Maximum Ratings and AC Electrical Characteristics. At this rate, the device achieves its top 500 ksps sample rate with 16 SCLK cycles per conversion frame. Operation above 16 MHz is not characterized and may cause timing violations or data corruption.
Does ADC124S051CIMMX/NOPB require an external reference voltage?
No, the ADC124S051CIMMX/NOPB uses its VA supply pin as the reference - the full-scale range is 0V to VA. This eliminates need for external reference components but requires clean, well-bypassed VA (1 µF + 0.1 µF) to maintain 72.5 dB SNR. No separate VREF pin exists.
How is channel selection implemented on ADC124S051CIMMX/NOPB?
Channel selection is controlled via a 3-bit address (ADD2:ADD0) loaded into the ADC124S051CIMMX/NOPB's control register on DIN during each conversion frame. The mapping is: 000 → IN1 (default), 001 → IN2, 010 → IN3, 011 → IN4. Bits 7–6 and 2–0 are don't-care.
What is the power-down current of ADC124S051CIMMX/NOPB at 3.6V?
At 3.6V supply and TA = 25°C, the ADC124S051CIMMX/NOPB draws 38 nA in shutdown mode (CS high), as confirmed in the Electrical Characteristics table. This ultra-low quiescent current enables multi-year battery life in intermittent-sampling applications.
Is ADC124S051CIMMX/NOPB pin-compatible with other devices in the ADC124Sxx family?
Yes - per Table 1 in the datasheet, ADC124S051CIMMX/NOPB is fully pin- and function-compatible with ADC124S021 and ADC122S101 within the same VSSOP-10 package. This allows drop-in replacement for rate or channel-count adjustments without PCB revision.
