Product details
Overview
ADC104S101CIMM/NOPB from Texas Instruments is a 10-bit, 4-channel successive-approximation ADC with serial SPI-compatible interface, operating at 500 ksps to 1 Msps sample rates, 2.7V–5.25V single supply, and −40°C to +85°C industrial temperature range - used for multi-sensor data acquisition in portable instrumentation.
For engineers reviewing the ADC104S101CIMM/NOPB datasheet, ADC104S101CIMM/NOPB pinout, ADC104S101CIMM/NOPB application, or ADC104S101CIMM/NOPB equivalent, key selection considerations include guaranteed no-missing-codes performance, channel-to-channel crosstalk <−78 dB, shutdown current as low as 33 nA, and VSSOP-10 package compatibility with space-constrained PCB layouts.
Technical Context
The ADC104S101CIMM/NOPB implements a charge-redistribution SAR architecture with integrated track-and-hold, supporting four analog inputs (IN1–IN4) via internal multiplexer. It uses straight binary output coding and operates with SPI/QSPI/MICROWIRE-compatible timing, requiring integer multiples of 16 SCLK cycles per conversion frame.
Conversion begins on CS falling edge; first 3 SCLK cycles perform input acquisition (track mode), followed by 13 cycles for hold, successive approximation, and MSB-first serial readout. Power-down is activated when CS is high, reducing supply current to ≤33 nA at 3.6V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Resolution | 10-bit with guaranteed no missing codes - ensures full dynamic range utilization without code gaps in sensor measurement systems. |
| Sample Rate Range | 500 ksps to 1 Msps - supports flexible throughput tuning across battery-powered and real-time control applications. |
| DNL / INL (Typ) | +0.26/−0.16 LSB / +0.4/−0.1 LSB - enables high-accuracy DC measurements with minimal code-width deviation. |
| SNR (Typ) | 61.7 dB at 40.3 kHz - delivers >9.9 ENOB for precision analog signal digitization in noisy environments. |
| Power (3V / 5V) | 3.9 mW / 11.4 mW normal mode; 0.12 µW / 0.47 µW shutdown - allows aggressive power gating in intermittent-sampling systems. |
| Analog Input Range | 0 V to VA - eliminates need for external level-shifting when using single-supply sensor interfaces. |
| Channel Crosstalk | −78 dB at 40.3 kHz - ensures independent channel integrity during simultaneous multi-signal monitoring. |
Pinout & Package
ADC104S101CIMM/NOPB is housed in a 10-lead VSSOP (Package Number DGS0010A), 3.0 mm × 3.0 mm × 0.9 mm body, 0.5 mm pitch, thermally enhanced with exposed pad (not electrically connected).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| CS | Chip Select | Falling-edge-triggered frame initiator; controls conversion start, serial framing, and automatic power-down when high. |
| SCLK | Serial Clock | Master-controlled clock (50 kHz–16 MHz); governs acquisition timing, conversion sequencing, and synchronous data I/O. |
| DOUT | Digital Output | MSB-first serial data output; tri-state when CS high; active only during CS-low frames. |
| DIN | Digital Input | Loads 8-bit control register (channel select ADD2:ADD0) on rising SCLK edges within each frame. |
| IN1–IN4 | Analog Inputs | Four single-ended inputs referenced to VA; each accepts 0 V to VA range with ±1 µA max DC leakage. |
| VA | Analog Supply | Single 2.7V–5.25V supply serving as reference and power rail; requires local 1 µF + 0.1 µF bypassing. |
| GND | Ground Return | Common return for analog and digital circuitry; must be low-impedance connection to minimize noise coupling. |
Key Features
| Feature | Design Value |
|---|---|
| Full-speed specification across 500 ksps–1 Msps | Eliminates derating uncertainty - all AC/DC specs (SNR, THD, crosstalk) validated across entire operational sample rate range. |
| Channel-to-channel offset & FSE match | OEM ≤ ±0.6 LSB and FSEM ≤ ±0.5 LSB - enables calibrated multi-channel systems without per-channel gain/offset compensation. |
| Low-power shutdown mode | 33 nA typical at 3.6V - supports microamp-level system sleep states while retaining fast wake-up (<16 SCLK cycles) to first valid conversion. |
| Integrated track-and-hold with 33 pF input capacitance (track) | Reduces external anti-aliasing filter complexity and enables direct connection to moderate-impedance sensors (≤1 kΩ recommended). |
| Straight binary output format | Removes software overhead for two's-complement conversion - simplifies firmware handling in 8-/16-bit microcontroller environments. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 4-channel SAR ADC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADC104S051CIMM/NOPB | Same pinout, 200–500 ksps max sample rate; lower power (2.8 mW @ 3V) but reduced SNR (60.5 dB). | Better suited for cost-sensitive, lower-throughput systems where 500 ksps ceiling is sufficient. | Select when system sampling requirement is ≤500 ksps and ultra-low power is prioritized over SNR margin. |
| ADC124S101CIMM/NOPB | Pin-compatible 12-bit upgrade; higher resolution (12-bit), same 500 ksps–1 Msps range, but higher power (5.1 mW @ 3V) and larger INL (±0.8 LSB). | Required when system demands ≥12-bit precision for extended dynamic range or calibration headroom. | Choose for applications needing >10-bit resolution - e.g., high-accuracy strain gauge or precision thermocouple measurement - accepting higher power and slightly degraded linearity. |
Compared with ADC104S051CIMM/NOPB, the ADC104S101CIMM/NOPB delivers 1.2 dB higher SNR and full 1 Msps capability at modest power increase; versus ADC124S101CIMM/NOPB, it trades 2 bits of resolution for 30% lower power and tighter INL, making it optimal for 10-bit–critical, power-constrained designs.

FAQ
What is the absolute maximum supply voltage for ADC104S101CIMM/NOPB?
The absolute maximum VA supply voltage for ADC104S101CIMM/NOPB is 6.5 V, though operational specification is limited to +2.7 V to +5.25 V. Exceeding 5.25 V may cause parametric degradation or damage, and operation above 6.5 V violates Absolute Maximum Ratings and risks permanent failure. Always maintain VA within the specified operating range for guaranteed performance and reliability of ADC104S101CIMM/NOPB.
Does ADC104S101CIMM/NOPB require an external reference voltage?
No, ADC104S101CIMM/NOPB uses its VA supply pin as the internal reference - the full-scale range is 0 V to VA, and LSB = VA/1024. No external reference is needed, simplifying BOM and layout. However, supply noise directly impacts SNR, so proper bypassing (1 µF + 0.1 µF near VA) and clean linear regulation are essential to achieve the specified 61.7 dB SNR for ADC104S101CIMM/NOPB.
How many SCLK cycles are required for one complete conversion and readout of ADC104S101CIMM/NOPB?
A complete conversion and readout cycle for ADC104S101CIMM/NOPB requires exactly 16 SCLK cycles per frame: first 3 cycles for track-mode acquisition, then 13 cycles for hold, conversion, and MSB-first serial output. The device expects integer multiples of 16 SCLK cycles while CS is low; non-multiple counts will corrupt timing and yield invalid data from ADC104S101CIMM/NOPB.
Can ADC104S101CIMM/NOPB perform simultaneous sampling across all four channels?
No, ADC104S101CIMM/NOPB performs sequential sampling via an internal multiplexer - only one channel (IN1–IN4) is sampled per conversion frame, selected by the 3-bit ADD2:ADD0 field loaded into the control register via DIN. True simultaneous sampling requires multiple independent ADCs or a dedicated simultaneous-sampling device; ADC104S101CIMM/NOPB provides rapid sequential acquisition with <1 µs inter-channel skew due to shared track-and-hold architecture.
What is the purpose of the DONTC bits in the ADC104S101CIMM/NOPB control register?
The DONTC bits (bits 7, 6, and 2–0) in the ADC104S101CIMM/NOPB control register are "don't care" fields - their logic state has no effect on device operation or channel selection. Only bits 5–3 (ADD2:ADD0) determine the next input channel (IN1–IN4). This allows firmware flexibility: any 8-bit value with correct ADD2:ADD0 can be written to DIN, simplifying register writes and reducing bit-manipulation overhead in ADC104S101CIMM/NOPB driver code.
