Product details
Overview
LTC1417ACGN#PBF from Analog Devices (formerly Linear Technology) is a 14-bit, 400ksps successive-approximation ADC with integrated sample-and-hold, precision 2.5V reference, and serial I/O interface. It operates from single 5V or ±5V supplies, delivers ±1.25LSB INL and ±1LSB DNL over temperature, and achieves 81dB S/(N+D) and –95dB THD at 200kHz Nyquist input-enabling high-fidelity data acquisition in isolated industrial sensors.
For engineers reviewing the LTC1417ACGN#PBF datasheet, LTC1417ACGN#PBF pinout, LTC1417ACGN#PBF application, or LTC1417ACGN#PBF equivalent, key selection criteria include unipolar/bipolar input range flexibility (0V–4.096V or ±2.048V), dual shutdown modes (Nap/Sleep), internal clock trimmed to 2.25µs max conversion time, and differential high-impedance analog inputs compatible with low-distortion op-amp drivers.
Technical Context
The LTC1417ACGN#PBF implements a capacitive DAC-based successive approximation architecture with zeroing switches for comparator offset nulling during acquisition. Its internal 2.5V reference (±10ppm/°C tempco) and REF COMP 4.096V output support ratiometric or absolute measurement schemes without external trimming.
Timing is controlled via active-low CONVST (with 40ns minimum pulse width), BUSY status flag, and RD-gated serial output. The device supports both internal clock mode (9.4MHz CLKOUT) and external clock synchronization (0.05–9MHz EXTCLKIN), enabling deterministic sampling in DSP- or microprocessor-coupled systems with FIFO buffering.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Resolution | 14-bit - delivers 16,384 discrete output codes for sub-millivolt voltage resolution in 4.096V full-scale range. |
| Sampling Rate | 400ksps - supports real-time capture of signals up to 200kHz Nyquist bandwidth with minimal aliasing risk. |
| INL / DNL | ±1.25LSB / ±1LSB max - ensures monotonicity and accurate DC transfer function across full temperature range (0°C to 70°C). |
| S/(N+D) | 81dB at 100kHz - corresponds to ~13.2 effective bits, enabling high-dynamic-range measurements in audio and spectrum instrumentation. |
| Power Dissipation | 20mW typ (unipolar) - enables thermally constrained designs; drops to 0.1µA in Sleep mode for ultra-low-power wake-on-event operation. |
| Analog Input Range | 0V to 4.096V (unipolar) or ±2.048V (bipolar) - matches standard sensor output ranges and eliminates level-shifting circuitry. |
| Reference Options | Internal 2.5V (±10ppm/°C) or external reference - provides system-level calibration flexibility and ratiometric accuracy when paired with resistive sensors. |
Pinout & Package
Package: 16-lead narrow-body SSOP (0.150" width), SO-8 footprint compatible, RoHS-compliant, lead-free (Pb-free) finish.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| AIN+ | Differential analog input (+) | Accepts high-impedance signal source; sampled simultaneously with AIN−; common-mode rejection ≥65dB improves noise immunity. |
| AIN− | Differential analog input (−) | Enables true differential measurement or single-ended operation (when grounded); defines input common-mode voltage range. |
| VREF | 2.50V reference output | Stable internal reference for ADC core; bypassed with 1µF to AGND; ±10ppm/°C tempco ensures accuracy over 0°C–70°C. |
| REFCOMP | 4.096V reference output | Provides precise full-scale reference for unipolar mode; requires 10µF tantalum + 0.1µF ceramic bypass for stability. |
| CONVST | Conversion start input | Active-low edge-triggered control; initiates SAR cycle; must remain low ≥40ns; timing-critical for synchronous sampling. |
| BUSY | Conversion status output | Active-high open-drain signal indicating conversion in progress; used for handshaking with microcontrollers or FIFO controllers. |
| DOUT | Serial data output | MSB-first 14-bit word synchronized to SCLK; tri-state controlled by RD; supports daisy-chaining multiple converters. |
| SHDN / RD | Power management inputs | SHDN low + RD low = Nap mode (750µA); SHDN low + RD high = Sleep mode (0.1µA); enables rapid wake-up or deep power-down. |
Key Features
| Feature | Design Value |
|---|---|
| Dual supply operation | Supports both 5V single-supply and ±5V bipolar configurations-eliminates need for separate rail generation in mixed-signal systems. |
| No missing codes | Guaranteed over full operating temperature range (0°C to 70°C)-ensures monotonic behavior critical for closed-loop control applications. |
| Low aperture jitter | 5ps RMS - preserves SNR at high input frequencies; essential for undersampling RF or IF signals beyond Nyquist. |
| High CMRR | 65dB over full input range - rejects common-mode noise from motor drives, industrial transducers, or long cable runs. |
| Onboard sample-and-hold | Acquisition time ≤500ns - allows direct connection to low-output-impedance amplifiers without external hold circuitry. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-resolution, medium-speed ADC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADS8325IPW | 16-bit, 100ksps, SPI interface, no internal reference, requires external 2.5V ref | Lower sampling rate but higher resolution; better for precision DC measurements than AC performance | Select when 16-bit static accuracy outweighs 400ksps throughput and internal reference convenience |
| MAX1166BCAP+ | 14-bit, 250ksps, internal reference, SPI-compatible, 16-pin TSSOP package | Slower sampling, lower power (12mW), no bipolar input support-unipolar only | Choose for space-constrained unipolar-only designs where 250ksps suffices and layout simplicity is prioritized |
Compared with ADS8325IPW and MAX1166BCAP+, the LTC1417ACGN#PBF uniquely combines 400ksps speed, internal 2.5V/4.096V references, bipolar/unipolar flexibility, and 81dB AC performance-making it optimal for real-time, mixed-signal industrial and test equipment where timing determinism and reference integration reduce BOM count.

FAQ
What is the operating temperature range for the LTC1417ACGN#PBF?
The LTC1417ACGN#PBF is rated for 0°C to 70°C ambient operation (Commercial grade). Its DC specifications-including ±1.25LSB INL and ±1LSB DNL-are guaranteed across this full range. For extended temperature applications (–40°C to 85°C), the LTC1417AIGN#PBF variant is specified.
Does the LTC1417ACGN#PBF require an external clock to operate?
No-the LTC1417ACGN#PBF includes an internal trimmed clock that supports 400ksps operation without external timing components. However, it also accepts an external conversion clock (0.05–9MHz) via EXTCLKIN for synchronous multi-device sampling or precise timing control in the LTC1417ACGN#PBF system.
How does the LTC1417ACGN#PBF handle unipolar versus bipolar input configurations?
The LTC1417ACGN#PBF automatically adapts: with single 5V supply (VDD = 5V, VSS = 0V), it accepts 0V to 4.096V unipolar inputs; with ±5V supplies (VDD = 5V, VSS = –5V), it accepts ±2.048V bipolar inputs. No configuration pins or registers are needed-the input range is supply-determined.
What are the power consumption modes of the LTC1417ACGN#PBF?
The LTC1417ACGN#PBF offers two user-selectable low-power states: Nap mode (750µA, fast wake-up) and Sleep mode (0.1µA, ultra-low leakage). Both are activated by pulling SHDN low while controlling RD-RD low selects Nap, RD high selects Sleep-giving designers granular control over latency vs. power trade-offs in the LTC1417ACGN#PBF.
Can the LTC1417ACGN#PBF interface directly with a microcontroller SPI port?
Yes-the LTC1417ACGN#PBF serial interface is SPI-compatible: DOUT is MOSI-equivalent, SCLK is clock input, and RD acts as chip select (active-high). While not a true 4-wire SPI slave, its timing (t11 ≤40ns, fSCLK up to 20MHz) allows seamless connection to most MCU SPI peripherals with minor software framing adjustments for the LTC1417ACGN#PBF 14-bit word.
