Product details
Overview
LTC1152IS8#PBF from Analog Devices (formerly Linear Technology) is a precision zero-drift operational amplifier with rail-to-rail input common-mode range and rail-to-rail output swing, designed for high-accuracy signal conditioning in low-voltage systems. It delivers 10 µV max input offset voltage, 100 nV/°C max offset drift, 115 dB min CMRR, 0.7 MHz gain-bandwidth product, and operates from 2.7 V to 14 V total supply voltage - enabling use in single-supply 3 V/5 V data acquisition front-ends.
For engineers reviewing the LTC1152IS8#PBF datasheet, LTC1152IS8#PBF pinout, LTC1152IS8#PBF application, or LTC1152IS8#PBF equivalent, key selection considerations include its internal charge pump enabling true rail-to-rail input operation beyond the rails, shutdown functionality reducing supply current to 1 µA, C-Load™ architecture supporting infinite capacitive load drive, and guaranteed –40°C to +85°C industrial temperature range in SO-8 package.
Technical Context
The LTC1152IS8#PBF employs a chopper-stabilized architecture with synchronized 2.3 kHz nulling clock and 4.7 MHz internal charge pump to extend input common-mode range beyond both supply rails while maintaining ultra-low DC errors. Its input stage uses auto-zeroing to correct offset in real time, achieving ±1 µV typical offset and <10 nV/°C typical drift.
The output stage features enhanced drive capability (±10 mA into 1 kΩ at 5 V) and open-loop output resistance as low as 140 Ω at 5 V, enabling stable rail-to-rail swing even under heavy loads. Compensation via external capacitor on COMP pin (Pin 5) allows configurable bandwidth limiting and infinite capacitive load driving.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Offset Voltage | ±10 µV max - ensures sub-mV error in precision gain stages without trimming. |
| Offset Drift | ±100 nV/°C max - maintains accuracy across industrial temperature range (–40°C to +85°C). |
| CMRR | 115 dB min - rejects common-mode noise in high-gain transducer interfaces. |
| Supply Voltage Range | 2.7 V to 14 V total - supports single 3 V/5 V or dual ±1.5 V/±2.5 V operation. |
| Gain-Bandwidth Product | 0.7 MHz - enables stable unity-gain buffer and low-noise amplification up to ~100 kHz. |
| Shutdown Current | 1 µA max - enables power gating in battery-powered sensor nodes. |
| Input Noise (0.1–10 Hz) | 2 µVP-P - suitable for DC-coupled thermocouple and strain gauge amplification. |
Pinout & Package
Package: 8-lead plastic SOIC (SO-8), surface-mount, standard op amp pinout compatible with industry footprint.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (SHDN) | Shutdown control input | CMOS-compatible logic input; pulls high internally (1 µA); drives output to high-Z and reduces ICC to 1 µA when low. |
| 2 (–IN) | Inverting input | Rail-to-rail common-mode range (extends 0.3 V beyond V– and V+); accepts signals at either supply rail. |
| 3 (+IN) | Non-inverting input | Same rail-to-rail CMR as –IN; enables true unity-gain buffer of 0–5 V signals from single 5 V supply. |
| 4 (V–) | Negative supply terminal | Connects to ground (single supply) or negative rail (dual supply); reference for internal charge pump. |
| 5 (COMP) | Compensation node | External capacitor (e.g., 0.1 µF to OUT) enables infinite capacitive load drive and bandwidth limiting. |
| 6 (OUT) | Amplifier output | Rail-to-rail swing into 1 kΩ; modeled as 140 Ω series resistance at 5 V; high-Z during shutdown. |
| 7 (V+) | Positive supply terminal | Accepts up to 14 V total supply; powers internal charge pump and output stage. |
| 8 (CP) | Charge pump output | Internally generates ~2 V above V+; optional 0.1 µF cap to V+ reduces 4.7 MHz feedthrough noise. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input CMR extending beyond rails | Enables direct amplification of signals at V– or V+, e.g., high-side current sensing without level-shifting. |
| C-Load™ architecture | Drives any capacitive load without oscillation - eliminates need for isolation resistors in ADC driver applications. |
| Internal 4.7 MHz charge pump | Generates boosted voltage internally; no external components required for rail-to-rail input operation. |
| Zero-drift auto-nulling at 2.3 kHz | Maintains ±1 µV typical offset over temperature and time - critical for long-term calibration stability. |
| Shutdown mode with high-Z output | Allows parallel MUX configuration of multiple LTC1152IS8#PBF units using SHDN pins - no external analog switches needed. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar zero-drift, rail-to-rail op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AD8628ARZ | No internal charge pump; input CMR limited to V– to V+ – 0.1 V - cannot sense at V+ rail. | Suitable for general-purpose precision buffering but not high-side current sensing or true rail-to-rail input at extremes. | Choose AD8628ARZ only if input signals stay ≥0.1 V away from rails and lower quiescent current (1.2 mA) is prioritized. |
| LTC2050CS8#PBF | Higher GBW (3 MHz), no shutdown pin, SO-8 package - but input CMR does not extend beyond rails. | Better for higher-speed precision applications (e.g., active filters), but lacks LTC1152IS8#PBF's rail-to-rail input flexibility and power gating. | Select LTC2050CS8#PBF when bandwidth >1 MHz is required and shutdown functionality is unnecessary. |
Compared with AD8628ARZ and LTC2050CS8#PBF, the LTC1152IS8#PBF uniquely combines rail-to-rail input beyond both rails, integrated shutdown, and C-Load™ infinite capacitive drive - making it the only choice for space-constrained, low-voltage, rail-referenced sensing with power management.

FAQ
What is the operating temperature range for the LTC1152IS8#PBF?
The LTC1152IS8#PBF is specified for operation from –40°C to +85°C, qualifying it for industrial-grade applications. This range is confirmed in the Absolute Maximum Ratings table and Electrical Characteristics sections of the official datasheet, where all "G"-marked parameters apply across this full interval. The "I" grade suffix in LTC1152IS8#PBF explicitly denotes this extended temperature capability.
Does the LTC1152IS8#PBF require external components for rail-to-rail input operation?
No, the LTC1152IS8#PBF does not require external components for rail-to-rail input operation. Its internal 4.7 MHz charge pump generates a voltage ~2 V above V+, enabling the input stage to accept signals beyond both supply rails - a feature explicitly stated in the device description and block diagram. External capacitors on CP (Pin 8) or COMP (Pin 5) are optional for noise reduction or bandwidth limiting, not for basic rail-to-rail functionality.
Can the LTC1152IS8#PBF drive large capacitive loads without external compensation?
Yes, the LTC1152IS8#PBF can drive infinite capacitive loads when externally compensated: connecting a 0.1 µF capacitor between COMP (Pin 5) and OUT (Pin 6) configures the amplifier for unlimited capacitive loading, as documented in Figure 3 and the Compensation/Bandwidth Limiting section. Without this capacitor, it remains stable up to 1000 pF - a key advantage of its C-Load™ architecture.
What is the purpose of the CP pin (Pin 8) on the LTC1152IS8#PBF?
The CP (Charge Pump) pin (Pin 8) provides access to the internal charge pump output, which runs ~2 V above V+. While not required for normal operation, adding a 0.1 µF capacitor from CP to V+ reduces 4.7 MHz switching feedthrough noise to negligible levels - a technique validated in the Typical Performance Characteristics and Application Circuits. Shorting CP to ground or V– must be avoided, as it destroys the part.
How does the shutdown feature affect the output state of the LTC1152IS8#PBF?
When the SHDN pin (Pin 1) is pulled low, the LTC1152IS8#PBF enters shutdown mode: supply current drops to 1 µA max, internal clocks halt, and the output stage transitions to a high-impedance (high-Z) state - verified in the Electrical Characteristics table under "IOSD Output Leakage Current" and the Shutdown section. This allows multiple LTC1152IS8#PBF units to share a common output bus in multiplexer configurations.
