Product details
Overview
LT1630IS8#PBF from Analog Devices (formerly Linear Technology) is a dual, rail-to-rail input and output precision operational amplifier with 30MHz gain-bandwidth product, 10V/µs slew rate, and 3.5mA supply current per amplifier. It operates from 2.7V single supply to ±15V, delivers ±35mA output drive, and maintains <525µV max input offset voltage over –40°C to +85°C - used in high-fidelity active filters and A/D driver stages.
For engineers reviewing the LT1630IS8#PBF datasheet, LT1630IS8#PBF pinout, LT1630IS8#PBF application, or LT1630IS8#PBF equivalent, key selection criteria include rail-to-rail input/output swing at low supply voltages, channel matching for dual-amplifier signal chains, CMRR >75dB across full common-mode range, and guaranteed performance over industrial temperature.
Technical Context
The LT1630IS8#PBF employs a patented dual-input-stage architecture: a PNP pair active near V– and an NPN pair active near V+, enabling true rail-to-rail input operation without phase reversal. Its output stage uses complementary push-pull transistors to achieve rail-to-rail swing while sourcing/sinking ≥35mA.
It features matched internal trimming for both input stages - one referenced to V– and one to V+ - delivering typical CMRR of 106dB at ±15V and ≥75dB across –40°C to +85°C. Open-loop gain exceeds 1000 V/mV into 10kΩ, minimizing gain error in precision closed-loop configurations.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain-Bandwidth Product | 30MHz - supports stable unity-gain buffer or 10x gain amplification up to 3MHz. |
| Slew Rate | 10V/µs - enables clean 10VP-P output at 100kHz without slewing distortion. |
| Input Offset Voltage | 525µV max - ensures ≤0.05% gain error in 1V full-scale instrumentation amplifiers. |
| Supply Range | 2.7V to ±15V - operates from single-cell Li-ion (3.0V) to industrial bipolar rails. |
| Output Drive Current | ±35mA min - directly drives 100Ω loads or 10nF capacitive DAC reference buffers. |
| CMRR | 75dB min (–40°C to +85°C) - rejects >99.7% of common-mode noise in sensor front-ends. |
| Input Noise Density | 6nV/√Hz at 1kHz - contributes <1.2µV RMS noise in 100kHz bandwidth applications. |
Pinout & Package
LT1630IS8#PBF is housed in an 8-lead plastic SO (SO-8) package with standard dual op amp pinout and JEDEC MS-012AC footprint (5.0mm × 6.2mm, 1.27mm pitch).

IC Role / Device Role / Timing Role: Single-supply unity-gain buffer isolating high-impedance sensor output from ADC sampling capacitor. Use Value: 3.5mA quiescent current per amplifier extends battery life; ±35mA peak drive settles 10nF load within 520ns (0.01%). |
| Rail-to-Rail Signal Buffering | Battery-Powered Instrumentation |
Use Scenario: Level-shifting and buffering of ±2.5V sensor output to 0–3.3V microcontroller ADC input. IC Role / Device Role / Timing Role: Inverting amplifier with rail-to-rail I/O operating from 3.3V single supply.

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual precision op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA2333AIDR | Zero-drift architecture; 0.02µV/°C offset drift vs. 5.5µV/°C for LT1630IS8#PBF; lower 1/f noise but 350kHz GBW. | Better for ultra-low-drift DC applications; unsuitable for >100kHz filtering or fast settling. | Select OPA2333AIDR when long-term DC stability dominates over speed and output drive. |
| AD8605ARZ-REEL7 | 10MHz GBW, 5V/µs slew rate, 1mA supply current; rail-to-rail I/O but only 10mA output drive. | Lower power and cost; insufficient for driving heavy capacitive loads or high-speed filters. | Select AD8605ARZ-REEL7 for low-power, general-purpose buffering where 30MHz bandwidth is unnecessary. |
Compared with OPA2333AIDR and AD8605ARZ-REEL7, the LT1630IS8#PBF uniquely balances high speed (30MHz), high output drive (±35mA), and rail-to-rail operation across industrial temperature - making it optimal for active filtering and precision A/D interfacing where both bandwidth and robust loading are required.

FAQ
What is the maximum supply voltage rating for the LT1630IS8#PBF?
The LT1630IS8#PBF has an absolute maximum total supply voltage (V+ to V–) of 36V. It is specified for operation from 2.7V single supply up to ±15V dual supply. Exceeding 36V risks permanent damage, and operation above ±15V requires derating per thermal limits defined in the datasheet.
Does the LT1630IS8#PBF support rail-to-rail input with a 3V single supply?
Yes, the LT1630IS8#PBF supports rail-to-rail input common-mode range - from V– (0V) to V+ (3V) - when operated on a 3V single supply. This is enabled by its dual-input-stage architecture (PNP + NPN), ensuring no phase reversal and maintaining CMRR >71dB across the full range.
What is the guaranteed input offset voltage specification for LT1630IS8#PBF over temperature?
The LT1630IS8#PBF guarantees a maximum input offset voltage of 775µV over the full industrial temperature range (–40°C to +85°C) at 3V or 5V supplies, and 1400µV at ±15V supplies. The typical value remains ≤250µV at 25°C, and drift is specified at ≤5.5µV/°C.
Can the LT1630IS8#PBF drive a 10nF capacitive load without instability?
The LT1630IS8#PBF can drive up to 1000pF capacitively without external compensation, as confirmed by typical performance plots (G16). For 10nF loads, series isolation resistance (≥100Ω) is required at the output to maintain stability; the device is not unity-gain stable into large capacitive loads without added isolation.
Is the LT1630IS8#PBF pin-compatible with standard dual op amp footprints?
Yes, the LT1630IS8#PBF uses the industry-standard 8-lead SO (SO-8) package with pin 1 = OUT A, pin 2 = –IN A, pin 3 = +IN A, pin 4 = V–, pin 5 = V+, pin 6 = OUT B, pin 7 = –IN B, pin 8 = +IN B - matching the pinout of LM358, TL072, and OP27 families in SO-8, enabling drop-in replacement in many designs.
