Product details
Overview
LTC1410IG#PBF from Analog Devices (formerly Linear Technology) is a 12-bit, 1.25 Msps successive-approximation ADC with differential input, internal ±2.5V bipolar range, 71 dB S/(N+D) at 625 kHz, ±1 LSB INL/DNL over temperature, and no pipeline delay. It serves as a high-speed data acquisition front-end in DSP systems requiring precise analog-to-digital conversion with low power shutdown.
For engineers reviewing the LTC1410IG#PBF datasheet, LTC1410IG#PBF pinout, LTC1410IG#PBF application, or LTC1410IG#PBF equivalent, key selection criteria include its 20 MHz full-power bandwidth, dual shutdown modes (7 mW Nap / 10 µW Sleep), internal 2.5 V reference with ±15 ppm/°C tempco, and µP-compatible parallel interface with BUSY strobe and no latency.
Technical Context
The LTC1410IG#PBF employs a capacitor-based successive approximation register (SAR) architecture with integrated differential sample-and-hold, enabling true differential acquisition up to 20 MHz. Its internal clock eliminates external timing synchronization requirements, and conversion is initiated by a falling edge on CONVST with BUSY indicating completion.
It supports both internal and external reference operation (2.25 V–2.75 V), features 60 dB common-mode rejection for noise suppression, and delivers guaranteed 1.25 Msps throughput with ≤800 ns total acquisition + conversion time. The device operates across –40°C to +85°C and uses ±5 V supplies (±4.75 V to ±5.25 V).

Pinout & Package
Package: 28-pin SO Wide (SW), RoHS-compliant, surface-mount plastic package with 0.3-inch body width and 0.050-inch lead pitch.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| +AIN (1) | Differential analog input positive | Accepts ±2.5 V input; sampled simultaneously with –AIN for common-mode noise rejection. |
| –AIN (2) | Differential analog input negative | Enables true differential acquisition; ground-referenced use possible but sacrifices CMRR. |
| VREF (3) | Internal 2.50 V reference output | Factory-trimmed bandgap reference; can be overdriven for external reference injection. |
| REFCOMP (4) | Reference amplifier compensation node | Requires 10 µF tantalum + 0.1 µF ceramic bypass to AGND for stability and low noise. |
| AGND (5) | Analog ground reference | Single-point star ground for analog section; must tie DGND and OGND here. |
| D11–D4 (6–13) | MSB-aligned parallel data outputs | Three-state, TTL/CMOS-compatible; driven only when CS = RD = LOW. |
| DGND (14) | Digital logic ground | Internal logic return; must connect to AGND at single point to prevent digital noise coupling. |
| D3–D0 (15–18) | LSB-aligned parallel data outputs | Completes 12-bit word; same drive characteristics and timing as D11–D4. |
| OGND (19) | Output driver ground | Separate return for output buffers; ties to AGND to minimize switching noise on analog ground. |
| NAP/SLP (20) | Shutdown mode select | High = Nap (fast wake-up, 7 mW); Low = Sleep (ultra-low power, 10 µW). |
| SHDN (21) | Power shutdown enable | Active-low control; effect determined by NAP/SLP state - no effect if high. |
| RD (22) | Data read strobe | Enables output drivers when CS is low; data valid on rising edge of BUSY. |
| CONVST (23) | Conversion start trigger | Falling-edge initiated; starts SAR cycle and disables input sampling during conversion. |
| CS (24) | Chip select | Must be low for CONVST and RD to be recognized; enables interface timing control. |
| BUSY (25) | Conversion status indicator | Active-low open-drain output; goes high at conversion completion; used for handshaking. |
| VSS (26) | Negative supply (–5 V) | Requires 10 µF tantalum + 0.1 µF ceramic bypass to AGND; absolute max –6 V. |
| DVDD (27) | Positive digital supply (5 V) | Shorted internally to AVDD; bypass required; absolute max +6 V. |
| AVDD (28) | Positive analog supply (5 V) | Shared with DVDD; separate bypassing recommended for optimal SNR. |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed SAR ADC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADS8325IPW | 16-bit, 100 ksps, SPI interface, single-ended input only; higher resolution but 12.5× slower sampling rate. | Best for precision DC-coupled measurements (e.g., strain gauge bridges), not high-speed AC signal capture. | Select when resolution > speed; avoid for Nyquist-limited or undersampling applications requiring ≥1 Msps. |
| MAX1186ETL+ | 12-bit, 1.5 Msps, 3.3 V single-supply, LVDS-compatible outputs; lacks internal reference and differential input stage. | Designed for portable, low-voltage systems with space-constrained layouts; requires external reference and driver amplifiers. | Select for battery-powered instruments needing lower supply voltage; verify external reference stability and driver bandwidth meet 20 MHz requirement. |
Compared with ADS8325IPW and MAX1186ETL+, the LTC1410IG#PBF uniquely combines 1.25 Msps throughput, integrated ±2.5 V reference, true differential inputs, and dual shutdown modes in a single ±5 V supply SO-28 package - making it optimal for industrial and telecom signal acquisition where speed, simplicity, and noise immunity are jointly critical.

FAQ
What is the operating temperature range for the LTC1410IG#PBF?
The LTC1410IG#PBF is rated for industrial operation from –40°C to +85°C. This range is explicitly defined in the Absolute Maximum Ratings table and confirmed across all DC and AC specifications marked with the "G" symbol in the datasheet. The part number suffix "I" denotes this industrial grade, distinguishing it from the commercial-grade LTC1410CG (0°C to 70°C). Thermal derating is not required within this span, and parameters like INL, DNL, and S/(N+D) are guaranteed over the full range.
Does the LTC1410IG#PBF require an external clock source?
No, the LTC1410IG#PBF does not require an external clock source. It contains a fully integrated, factory-trimmed internal clock that guarantees a maximum conversion time of 750 ns and a minimum sampling rate of 1.25 Msps. This eliminates timing synchronization complexity between external clocks and control signals like CS or RD, simplifying system design and improving robustness against clock jitter. The internal clock is used exclusively for the SAR conversion sequence and cannot be overridden or adjusted.
Can the LTC1410IG#PBF operate with a single +5 V supply?
No, the LTC1410IG#PBF requires dual ±5 V supplies (AVDD = DVDD = +5 V, VSS = –5 V) for specified operation. Its analog input range is ±2.5 V, and its internal reference and comparator circuitry depend on symmetric rails. While absolute maximum ratings allow VDD up to +6 V and VSS down to –6 V, operation outside ±4.75 V to ±5.25 V violates recommended conditions and degrades performance - including reduced S/(N+D), increased offset drift, and potential reference instability. Single-supply operation is not supported.
How does the NAP/SLP pin affect shutdown behavior in the LTC1410IG#PBF?
The NAP/SLP pin on the LTC1410IG#PBF selects between two distinct low-power states activated by the SHDN pin: when NAP/SLP is high, SHDN = LOW invokes Nap mode (7 mW, 200 ns wake-up); when NAP/SLP is low, SHDN = LOW invokes Sleep mode (10 µW, longer wake-up). This dual-mode architecture allows system designers to trade off wake-up latency against power savings based on application duty cycle - e.g., Nap for burst-mode sensing, Sleep for deep standby in battery-backed systems. Both modes retain register state and require no reinitialization.
Is the LTC1410IG#PBF pin-compatible with other members of the LTC1410 family?
Yes, the LTC1410IG#PBF is pin-compatible with all variants in the LTC1410 family sharing the same SW (28-pin SO Wide) package, including LTC1410CG, LTC1410CSW, and LTC1410ISW. All share identical pin functions, electrical characteristics, and timing specifications. The "I" suffix indicates industrial temperature grade, while "G" vs "SW" denotes lead finish (Pb-free vs leaded) and package variant - but mechanical and electrical interfaces remain identical. This allows drop-in replacement across temperature grades without PCB redesign.
