Product details
Overview
ADS8341EB/2K5 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 throughput rate, and 86dB SINAD. It operates from a single 2.7V–5V supply, features internal sample-and-hold, and targets precision data acquisition in portable instrumentation.
For engineers reviewing the ADS8341EB/2K5 datasheet, ADS8341EB/2K5 pinout, ADS8341EB/2K5 application, or ADS8341EB/2K5 equivalent, key selection criteria include its SSOP-16 package, 16-cycle conversion time, ±8 LSB integral linearity (ADS8341EB grade), shutdown mode (<15µW), and compatibility with external or internal clock modes for flexible system integration.
Technical Context
The ADS8341EB/2K5 implements a capacitive redistribution SAR architecture with integrated multiplexer, enabling configurable 4-channel single-ended or 2-channel differential analog input routing via SGL/DIF and A2–A0 control bits. Its CDAC-based conversion core achieves 16-bit resolution without trimming, supported by on-chip reference input (0.5V to VCC) and CMOS-compatible digital interface.
It supports two clock modes: external clock (up to 2.4MHz, 24 cycles/conversion) and internal clock (auto-generated, 8µs max conversion time). BUSY and DOUT are tri-stated when CS is high, and SHDN enables sub-15µW shutdown - critical for battery-powered systems requiring intermittent sampling.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Resolution | 16-bit - delivers 65,536 distinct output codes; LSB = 76µV at 5V reference. |
| Throughput Rate | 100kHz - supports real-time sampling of signals up to ~40kHz (Nyquist-limited) with full 16-bit accuracy. |
| SINAD | 86dB at 10kHz - ensures >14.3 effective number of bits (ENOB) for high-fidelity signal digitization. |
| Integral Linearity Error | ±6 LSB (typ), ±8 LSB (max) - guarantees monotonicity and <0.012% full-scale error across temperature. |
| Supply Range | 2.7V to 5V - enables direct operation from Li-ion (3.0–4.2V) or 3.3V/5V system rails without LDO overhead. |
| Power Dissipation | 3.2mW (typ @ 2.7V/100kHz), 10mW (typ @ 5V/100kHz) - optimized for low-duty-cycle portable logging. |
| Operating Temp | –40°C to +85°C - qualified for industrial and automotive-adjacent embedded environments. |
Pinout & Package
ADS8341EB/2K5 is housed in a 16-pin SSOP (DBQ) package with 0.65mm pitch, thermally enhanced for stable performance in compact layouts. Pin assignments are validated per TI SBAS136D datasheet Rev D.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| +VCC (Pins 1, 9) | Power supply input | Dual power pins reduce IR drop and improve PSRR; accepts 2.7V–5V single supply. |
| CH0–CH3 (Pins 2–5) | Analog input channels | Four independent inputs configurable as single-ended (vs COM) or differential pairs (e.g., CH0+/CH1–). |
| COM (Pin 6) | Analog ground reference | Sets zero-code voltage in single-ended mode; must be connected to clean analog ground or bias point. |
| SHDN (Pin 7) | Shutdown control | Active-low input; reduces quiescent current to <15µW when asserted - essential for ultra-low-power sleep states. |
| VREF (Pin 8) | Reference voltage input | Unbuffered input (0.5V–VCC); sets full-scale range (e.g., 0–2.5V); LSB scales linearly with VREF. |
| GND (Pins 10, 11) | Analog ground return | Dual GND pins isolate analog return path; must connect to low-impedance analog ground plane. |
| DOUT (Pin 12) | Serial data output | Tri-state CMOS output enabled only when CS is low; outputs MSB-first straight-binary code on DCLK falling edge. |
| BUSY (Pin 13) | Conversion status indicator | Active-high open-drain output signaling conversion in progress; remains functional even when CS is high (internal clock mode). |
| DIN (Pin 14) | Serial data input | Accepts 8-bit control byte (S-A2-A1-A0-xx-SGL/DIF-PD1-PD0); latched on DCLK rising edge. |
| CS (Pin 15) | Chip select | Active-low enable; initiates conversion sequence and enables DOUT/BUSY; controls register access timing. |
| DCLK (Pin 16) | Serial clock input | Drives data I/O and (in external mode) SAR conversion; max 2.4MHz; requires tACQ ≥1.5µs for valid sampling. |
Key Features
| Feature | Design Value |
|---|---|
| Configurable input topology | Software-selectable 4-channel single-ended or 2-channel differential via SGL/DIF bit - eliminates external mux hardware. |
| Internal sample-and-hold | Capacitive redistribution SAR architecture inherently includes track/hold - no external components required for anti-aliasing. |
| Flexible clock architecture | Supports both external clock (24-cycle deterministic timing) and internal clock (8µs max latency, processor-friendly readout). |
| Low-power shutdown | SHDN pin reduces supply current to <15µW - enables µA-level average power in duty-cycled sensor nodes. |
| Wide reference range | VREF accepts 0.5V–VCC, enabling scalable full-scale ranges (e.g., 0–1.25V for low-noise sensor interfaces). |
| Industrial temperature grade | Specified over –40°C to +85°C with guaranteed INL (±8 LSB), offset match (≤4 LSB), and gain match (≤4 LSB). |

FAQ
What is the maximum sampling rate of the ADS8341EB/2K5?
The ADS8341EB/2K5 achieves a maximum throughput rate of 100kHz, corresponding to a minimum conversion time of 10µs. This is realized using a 24-cycle external clock sequence at 2.4MHz DCLK or an internal clock with 8µs max conversion latency. At lower sample rates, power consumption scales down proportionally - e.g., 300µA quiescent current at 12.5kHz.
Does the ADS8341EB/2K5 require an external reference voltage?
Yes, the ADS8341EB/2K5 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 (e.g., 0–2.5V with 2.5V reference). The device does not include an internal reference; reference accuracy and noise directly impact overall system ENOB and offset stability.
How does the SHDN pin function on the ADS8341EB/2K5?
The SHDN pin on the ADS8341EB/2K5 is an active-low input that places the device into ultra-low-power shutdown mode, reducing supply current to under 15µW. When deasserted (high), normal operation resumes instantly - no wake-up delay or reinitialization is needed, and the first conversion after exit is fully valid. This makes ADS8341EB/2K5 ideal for battery-powered systems with intermittent sampling requirements.
Can the ADS8341EB/2K5 perform differential measurements?
Yes, the ADS8341EB/2K5 supports true 2-channel differential input mode via the SGL/DIF control bit. When SGL/DIF = LOW, pairs such as CH0/CH1 or CH2/CH3 become differential inputs (+IN/–IN), providing common-mode rejection and improved noise immunity. Input voltage ranges remain within specification: –0.2V to +VCC+0.2V on +IN and –0.2V to +1.25V on –IN.
What package type is used for the ADS8341EB/2K5?
The ADS8341EB/2K5 is packaged in a 16-pin SSOP (Shrink Small Outline Package) with DBQ designation, 0.65mm lead pitch, and exposed thermal pad. This surface-mount package measures 4.9mm × 3.9mm and is optimized for automated assembly and thermal performance in compact PCB layouts - consistent with TI's industrial-grade packaging standards.
