Product details
Overview
ADS8341EB/2K5G4 from Texas Instruments is a 16-bit, 4-channel SAR analog-to-digital converter with synchronous serial interface, single-ended or 2-channel differential input capability, 100kHz maximum throughput rate, and 86dB SINAD at 10kHz - designed for precision data acquisition in battery-powered measurement systems.
For engineers reviewing the ADS8341EB/2K5G4 datasheet, ADS8341EB/2K5G4 pinout, ADS8341EB/2K5G4 application, or ADS8341EB/2K5G4 equivalent, key selection considerations include its SSOP-16 package, 2.7V–5V single-supply operation, internal/external clock mode flexibility, shutdown current <15µW, and guaranteed –40°C to +85°C performance.
Technical Context
The ADS8341EB/2K5G4 implements a capacitive redistribution SAR architecture with integrated sample-and-hold, supporting both external and internal clock modes via PD1/PD0 control bits. Its four-channel analog multiplexer enables configurable single-ended (CHx-to-COM) or differential (CHx-to-CHy) input routing under SGL/DIF bit control.
Digital interface uses an 8-bit control byte (S-A2-A1-A0-xx-SGL/DIF-PD1-PD0) followed by 16-bit straight-binary output, synchronized to DCLK with BUSY signaling. Conversion timing is 24 clock cycles in external mode or up to 8µs in internal mode, with acquisition time as low as 900ns (+5V) or 1.5µs (+2.7V).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Resolution | 16-bit - delivers 65,536 distinct digital codes; LSB = 76µV at 5V reference. |
| Throughput Rate | 100kHz - supports real-time sampling of signals up to ~40kHz (Nyquist-limited), with 24-clock-cycle conversion cycle. |
| SINAD | 86dB at 10kHz - ensures ≥14.3 effective number of bits (ENOB) for high-fidelity signal digitization. |
| Input Configuration | 4-channel single-ended or 2-channel differential - selectable via SGL/DIF and A2–A0 bits; COM pin sets zero-reference point. |
| Supply Range | 2.7V to 5V - enables direct interfacing with Li-ion, 3.3V, or 5V logic domains without level-shifting. |
| Power Dissipation | 3.2mW typical at +2.7V/100kHz; <15µW in shutdown - critical for multi-day battery life in portable loggers. |
| Reference Range | 0.5V to VCC - allows scalable input full-scale range (e.g., 0–2.5V or 0–5V); unbuffered VREF input draws ≤40µA. |
Pinout & Package
ADS8341EB/2K5G4 is housed in a 16-pin SSOP (Shrink Small Outline Package) with 0.65mm pitch, JEDEC MO-153 compliant, footprint code DBQ. The package is RoHS-compliant and rated for –40°C to +85°C industrial operation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 9 | +VCC | Primary power supply input; accepts 2.7V–5V; dual pins reduce IR drop and improve PSRR. |
| 2–5 | CH0–CH3 | Analog input channels; configurable as single-ended (vs COM) or differential pairs (e.g., CH0–CH1). |
| 6 | COM | Common-mode reference for single-ended inputs; sets zero-code voltage; connect to system ground or bias point. |
| 7 | SHDN | Active-low shutdown control; reduces supply current to <15µW when pulled low; no wake-up delay required. |
| 8 | VREF | Unbuffered reference input; determines full-scale range (0V to VREF); input current scales with fSAMPLE and VREF. |
| 10, 11 | GND | Analog ground return; separate pins minimize noise coupling between analog and digital sections. |
| 12 | DOUT | Serial data output; tri-stated when CS is high; outputs MSB-first straight-binary on DCLK falling edge. |
| 13 | BUSY | Open-drain status indicator; goes high during conversion (external mode) or low-to-high transition (internal mode). |
| 14 | DIN | Serial data input; latches control byte on DCLK rising edge; accepts CMOS levels up to 5.5V regardless of VCC. |
| 15 | CS | Chip select; initiates conversion sequence; controls DOUT/BUSY enable/disable timing per timing specs. |
| 16 | DCLK | External serial clock input; drives data I/O and (in external mode) SAR conversion timing; max 2.4MHz. |
Key Features
| Feature | Design Value |
|---|---|
| Pin-compatible with ADS7841 | Enables drop-in upgrade path from 12-bit to 16-bit resolution without PCB redesign. |
| Configurable clock mode | Selectable internal or external conversion clock via PD1/PD0 bits - simplifies MCU integration or enables deterministic timing. |
| Channel-to-channel isolation | 100dB at 50kHz - prevents crosstalk in multi-sensor monitoring where adjacent channels measure independent signals. |
| Low-noise architecture | 86dB SINAD and 92dB SFDR - preserves signal integrity in test equipment and precision sensor interfaces. |
| Flexible reference scaling | VREF adjustable from 0.5V to VCC - supports wide dynamic range inputs while maintaining 16-bit resolution. |
| Auto power-down mode | PD1=PD0=0 enables automatic shutdown between conversions - cuts average current in low-duty-cycle sampling. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit SAR ADC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADS8342EB/2K5 | Same pinout and interface, but 2-channel (not 4-channel) input; identical 16-bit resolution, 100kHz rate, and SSOP-16 package. | Best suited for dual-signal systems (e.g., voltage/current pair) where channel count reduction is acceptable. | Select ADS8342EB/2K5 when only two analog inputs are needed - saves board area and simplifies firmware channel management. |
| ADS8325IPW | 16-bit, 1-MSPS SAR ADC in TSSOP-20; requires external reference; no integrated multiplexer; higher speed but higher power (15mW @ 5V). | Targets high-speed applications like motor control feedback or fast transient capture where >100kHz sampling is mandatory. | Choose ADS8325IPW only if throughput >100kHz is required; not pin-compatible and lacks onboard mux - demands redesign. |
Compared with ADS8342EB/2K5, the ADS8341EB/2K5G4 provides two extra analog input channels without increasing package size or interface complexity; versus ADS8325IPW, it trades speed for lower power and integrated channel selection - making it optimal for portable, multi-sensor, battery-limited designs.

FAQ
What is the maximum sampling rate supported by the ADS8341EB/2K5G4?
The ADS8341EB/2K5G4 supports a maximum throughput rate of 100kHz, achieved with a 2.4MHz DCLK in external clock mode. This corresponds to a minimum conversion time of 24 clock cycles (9.6µs), enabling reliable digitization of signals up to ~40kHz under Nyquist criteria. At lower clock rates, throughput scales linearly.
Does the ADS8341EB/2K5G4 require an external reference voltage?
Yes, the ADS8341EB/2K5G4 requires an external reference voltage applied to the VREF pin. It accepts any stable voltage from 0.5V to VCC, directly setting the full-scale input range (0V to VREF). The reference is unbuffered and draws up to 40µA, so a low-impedance source (e.g., REF5025 or REF3025) is recommended for best performance.
How does the ADS8341EB/2K5G4 handle differential input configurations?
The ADS8341EB/2K5G4 supports true differential inputs using two of its four analog channels (e.g., CH0 and CH1) with the SGL/DIF bit set LOW. In this mode, the converter measures the voltage difference between the selected pair, rejecting common-mode noise. The COM pin is unused in differential mode, and input ranges are ±0.2V on the negative input and –0.2V to VCC+0.2V on the positive input.
Can the ADS8341EB/2K5G4 operate from a 3.3V supply?
Yes, the ADS8341EB/2K5G4 is fully specified for operation from 2.7V to 5V, including standard 3.3V supplies. At +3.3V, typical power dissipation is ~4.5mW at 100kHz, and all electrical characteristics - including 16-bit no-missing-codes performance and 86dB SINAD - remain guaranteed across –40°C to +85°C.
What is the purpose of the SHDN pin on the ADS8341EB/2K5G4?
The SHDN (shutdown) pin on the ADS8341EB/2K5G4 is an active-low control that places the device into an ultra-low-power state drawing <15µW when asserted. It operates independently of CS or power-down mode bits, allowing rapid entry/exit from standby without configuration overhead - ideal for duty-cycled sensing in battery-powered ADS8341EB/2K5G4 applications.
