Product details
Overview
LTC6248IMS#PBF from Analog Devices is a quad rail-to-rail input/output operational amplifier optimized for low-power, high-speed signal conditioning in 2.5V–5.25V systems. It delivers 180MHz gain-bandwidth product, 90V/µs slew rate, 4.2nV/√Hz input voltage noise, 1mA quiescent current per amplifier, and full rail-to-rail swing at ±25mA output drive - enabling precision ADC driving and active filtering in battery-powered instrumentation.
For engineers reviewing the LTC6248IMS#PBF datasheet, LTC6248IMS#PBF pinout, LTC6248IMS#PBF application, or LTC6248IMS#PBF equivalent, this page provides verified package mapping (16-lead MSOP), confirmed quad-channel pin assignment, temperature-rated performance (–40°C to +85°C), and validated alternatives for low-noise, unity-gain-stable op amp replacement in space-constrained analog front-ends.
Technical Context
The LTC6248IMS#PBF employs dual-input-stage architecture: a PNP pair active from V– to ~1.2V below V+, and an NPN pair taking over near V+ to maintain rail-to-rail common-mode range (0V to VS). This topology enables seamless input crossover without discontinuity in offset or bias current across the full supply range.
Each of its four amplifiers features independent shutdown control (SHDN pins), fast 5µs turn-on/2µs turn-off timing, and maintains 120MHz closed-loop bandwidth (AV = 1) with 110dB CMRR and 73dB PSRR - supporting stable operation in mixed-signal PCB environments with shared power rails and dynamic load switching.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain-Bandwidth Product | 180MHz - supports stable unity-gain configurations up to 120MHz closed-loop bandwidth for high-fidelity signal acquisition. |
| Slew Rate | 90V/µs - enables clean 2V step response in ≤74ns (0.1%) for fast-settling sensor interfaces and pulse amplification. |
| Input Voltage Noise | 4.2nV/√Hz @ 100kHz - ensures minimal added noise in low-level signal chains such as precision current sensing or microphone preamps. |
| Quiescent Current | 1mA per amplifier - allows four-channel operation at only 4mA total, critical for always-on portable medical or IoT edge nodes. |
| Supply Range | 2.5V to 5.25V - compatible with single Li-ion (3.0–4.2V), USB-powered (3.3V), and dual-supply (±2.5V) architectures without level-shifting. |
| Output Drive | ±50mA - drives 1kΩ loads to rail while maintaining <150mV saturation voltage, sufficient for direct ADC buffer or active filter termination. |
| Operating Temp | –40°C to +85°C - qualified for industrial automation, automotive cabin electronics, and outdoor sensor hubs without derating. |
Pinout & Package
Package: 16-Lead Plastic MSOP (MS package), 3mm × 4.9mm × 1.1mm body, exposed pad connected to V–.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT A | Amplifier A output - rail-to-rail capable, drives 50mA, requires local 0.1µF bypass to V–. |
| 2 | V– | Negative supply pin - connects to system ground or negative rail; exposed pad must be soldered to PCB thermal plane. |
| 3 | +IN A | Non-inverting input of Amp A - accepts signals from V– to V+, no external clamping required. |
| 4 | V+ | Positive supply pin - accepts 2.5V–5.25V; decoupling to V– essential for high-frequency stability. |
| 5 | +IN B | Non-inverting input of Amp B - electrically isolated from Amp A; shares same V+ and V– rails. |
| 6 | –IN B | Inverting input of Amp B - differential pair with +IN B; matched offset and bias current within channel pair. |
| 7 | OUT B | Amplifier B output - identical drive capability and noise performance as OUT A. |
| 8 | SHDN B | Active-low shutdown for Amp B - pulls to V– to disable; draws only 42µA in shutdown state. |
| 9 | OUT D | Amplifier D output - fourth independent channel; pin 9 is top-row rightmost in standard MSOP orientation. |
| 10 | –IN D | Inverting input of Amp D - part of channel D pair; matches Amp A/B performance per datasheet specs. |
| 11 | +IN D | Non-inverting input of Amp D - full rail-to-rail common-mode range, same as all other inputs. |
| 12 | V– | Second V– connection - redundant bond wire; must connect to same net as Pin 2 for low-impedance return path. |
| 13 | +IN C | Non-inverting input of Amp C - third channel; layout symmetry recommended to minimize crosstalk (<–90dB @ 1MHz). |
| 14 | –IN C | Inverting input of Amp C - matched to +IN C; offset voltage match between C/D channels is ±700µV max. |
| 15 | OUT C | Amplifier C output - fully specified for 120MHz BW and 90V/µs SR under same conditions as other channels. |
| 16 | SHDN C | Active-low shutdown for Amp C - independent control; SHDN B and SHDN C allow selective channel disabling. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad rail-to-rail op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AD8604ARUZ | Lower GBW (8MHz), higher supply current (1.3mA), no shutdown pins, 500µV max VOS vs 1mV for LTC6248IMS#PBF. | Targeted at precision DC-coupled applications (e.g., strain gauge bridges), not high-speed signal chains. | Select AD8604ARUZ when ultra-low offset and drift dominate over speed; avoid for >100kHz closed-loop use. |
| TSV914IQDT | Higher GBW (20MHz), lower noise (12nV/√Hz), no shutdown, 1.8V–5.5V supply, but only 50mA output drive at 3.3V. | Optimized for cost-sensitive consumer electronics with moderate bandwidth needs (e.g., audio codecs, touch controllers). | Choose TSV914IQDT for sub-$0.50 BOM targets where 20MHz BW suffices and shutdown is unnecessary. |
Compared with AD8604ARUZ and TSV914IQDT, the LTC6248IMS#PBF uniquely combines 180MHz bandwidth, 1mA/channel efficiency, per-amplifier shutdown, and rail-to-rail I/O in a single quad package - making it the only option for space-constrained, battery-powered systems requiring both speed and precision.

FAQ
What is the maximum supply voltage for the LTC6248IMS#PBF?
The LTC6248IMS#PBF supports a total supply voltage range of 2.5V to 5.25V. Absolute maximum rating is 5.5V across V+ to V–. Operation above 5.25V voids specifications and risks permanent damage per Absolute Maximum Ratings table. For dual-supply use, ±2.5V (5V total) is the recommended maximum.
Does the LTC6248IMS#PBF support true rail-to-rail input and output?
Yes, the LTC6248IMS#PBF supports true rail-to-rail input (0V to VS) and output (within 55mV of each rail at no load, 160mV at 25mA sink/source). Its dual-input-stage architecture (PNP + NPN) ensures continuous operation across the full common-mode range without crossover distortion or offset discontinuity.
How many independent shutdown pins does the LTC6248IMS#PBF have?
The LTC6248IMS#PBF has two independent active-low shutdown pins: SHDN B (Pin 8) controls Amplifiers A and B; SHDN C (Pin 16) controls Amplifiers C and D. Each reduces the respective pair's supply current to 42µA, enabling granular power management in multi-channel systems.
What is the typical input voltage noise density of the LTC6248IMS#PBF?
The LTC6248IMS#PBF has a typical input voltage noise density of 4.2nV/√Hz at 100kHz, measured with VCM = half-supply. This value remains stable across temperature and supply voltage variations, making it suitable for low-noise applications like precision current sensing and microphone preamplification.
Is the LTC6248IMS#PBF pin-compatible with other members of the LTC6246/LTC6247/LTC6248 family?
No - the LTC6248IMS#PBF uses a 16-lead MSOP package with dedicated pins for four amplifiers and two shutdown controls. The LTC6246 (single, TSOT-23) and LTC6247 (dual, MS8/UTDFN/TSOT-23) use different footprints and pinouts. Direct substitution requires PCB redesign; functional equivalence exists only at the circuit level.
