Product details
Overview
LT1216CS#PBF from Analog Devices (formerly Linear Technology) is a quad precision operational amplifier optimized for single-supply operation with 23MHz gain-bandwidth product, 50V/µs slew rate, and rail-to-rail output swing to ground while sinking current. It features 450µV max input offset voltage, 10µV/°C max drift, and supports 3.3V, 5V, and ±15V supplies - ideal for high-accuracy signal conditioning in battery-powered instrumentation.
For engineers reviewing the LT1216CS#PBF datasheet, LT1216CS#PBF pinout, LT1216CS#PBF application, or LT1216CS#PBF equivalent, key selection criteria include guaranteed 0.01% settling in 480ns (10V step), 30mA output drive into low-impedance loads, DC precision enabling trimless 16-bit DAC interfaces, and compatibility with ground-referenced input stages in single-supply active filters and photo diode amplifiers.
Technical Context
The LT1216CS#PBF implements a bipolar input stage with complementary NPN/PNP transistors enabling wide common-mode input range (including ground) and fast large-signal response. Its internal compensation ensures stable unity-gain operation with ≥45° phase margin across supply voltages from 2.5V to 36V total.
Each of the four amplifiers operates independently with matched AC/DC characteristics; channel separation exceeds 128dB at 1kHz under ±15V conditions. The device maintains specified performance over –40°C to +85°C without requiring external trimming components.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain-Bandwidth Product | 23MHz typical - enables stable closed-loop gain up to 10× at 2.3MHz or unity gain at 23MHz. |
| Slew Rate | 50V/µs typical - supports clean 10V step response within 480ns to 0.01% accuracy. |
| Input Offset Voltage | 450µV maximum - ensures ≤3 LSB error in 10V full-scale 16-bit systems. |
| Supply Current per Amp | 6.6mA maximum - allows four-channel operation at <27mA total on 5V supply. |
| Output Drive Current | ±30mA minimum - drives 500Ω loads while maintaining linearity and low distortion. |
| Input Noise Density | 12.5nV/√Hz at 1kHz - preserves SNR in low-level sensor signal amplification. |
| Common-Mode Range | Includes ground (V–) and extends to V+ – 1.5V - simplifies single-supply level-shifting design. |
Pinout & Package
LT1216CS#PBF is housed in a 16-lead plastic SO (SO-16) surface-mount package with JEDEC MS-013AC footprint, 1.27mm pitch, and 10.3mm × 7.5mm body size. Thermal resistance θJA = 100°C/W in still air.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT A | Amplifier A output - capable of sourcing/sinking 30mA, swings to ground when sinking. |
| 2 | –IN A | Inverting input of Amp A - high-impedance node; bias current ≤600nA. |
| 3 | +IN A | Non-inverting input of Amp A - accepts common-mode signals down to V–. |
| 4 | V+ | Positive supply rail - accepts 2.5V to 36V total supply; bypass with 0.01µF near pin. |
| 5 | +IN B | Non-inverting input of Amp B - electrically isolated from other channels. |
| 6 | –IN B | Inverting input of Amp B - matched offset and noise performance vs Amp A. |
| 7 | OUT B | Amplifier B output - identical drive capability and settling behavior as OUT A. |
| 8 | NC | No connect - no internal connection; leave unconnected or grounded per layout best practice. |
| 9 | OUT D | Amplifier D output - fourth independent output; shares same electrical specs as OUT A. |
| 10 | –IN D | Inverting input of Amp D - fully characterized for DC precision and AC performance. |
| 11 | +IN D | Non-inverting input of Amp D - supports rail-to-ground input common-mode range. |
| 12 | V– | Negative supply rail - referenced to system ground in single-supply configurations. |
| 13 | +IN C | Non-inverting input of Amp C - third channel with identical input structure. |
| 14 | –IN C | Inverting input of Amp C - low input bias current enables high-impedance sensor interfaces. |
| 15 | OUT C | Amplifier C output - delivers same 30mA drive and 480ns 0.01% settling as other outputs. |
| 16 | NC | No connect - unused pad; no internal connection; avoid routing signals here. |

IC Role / Device Role / Timing Role: Single amplifier configured as TIA with 10MΩ feedback resistor and 12.5nV/√Hz input noise floor. Use Value: Low input voltage noise minimizes contribution to total system noise; rail-to-ground output accommodates zero-biased diode configuration. |
| DAC Current-to-Voltage Converters | Battery-Powered Instrumentation |
Use Scenario: Converting 16-bit current-output DAC (e.g., AD5422) into precise 0–10V analog output for PLC analog I/O module. IC Role / Device Role / Timing Role: Precision op-amp serving as I-to-V converter with 450µV max VOS limiting full-scale error to ≤3 LSB.

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad precision op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OP4177ARUZ | Lower 7.5nV/√Hz noise, 1.3MHz GBW, 0.75V/µs slew; laser-trimmed VOS = 25µV max. | Better for ultra-low-noise DC-coupled applications (e.g., weigh scales); insufficient speed for >100kHz active filters. | Select OP4177ARUZ when sub-µV offset and ultra-low noise dominate; avoid when >1MHz bandwidth or fast settling required. |
| TLV2464IDR | CMOS input (0.5pA IB), 6.4MHz GBW, 1.6V/µs slew, 3.3V–6V only; VOS = 1.5mV max. | Superior for high-impedance pH electrode or piezoelectric sensor interfaces; lacks speed and precision for 16-bit DAC support. | Select TLV2464IDR for nanoamp-input, low-voltage-only designs; avoid where 450µV VOS or 50V/µs slew are mandatory. |
Compared with OP4177ARUZ and TLV2464IDR, LT1216CS#PBF uniquely balances high speed (23MHz/50V/µs), precision (450µV VOS), and single-supply robustness - making it the only option among the three qualified for trimless 16-bit DAC interfaces with sub-500ns settling.

FAQ
What is the maximum supply voltage rating for LT1216CS#PBF?
The LT1216CS#PBF has an absolute maximum total supply voltage (V+ to V–) of 36V. It is fully functional and characterized from 2.5V to 36V total supply, with guaranteed specifications at 3.3V, 5V, and ±15V. Operation below 2.5V is possible but degrades common-mode range and phase margin; minimum recommended operating voltage is 2.7V over the full –40°C to +85°C temperature range.
Does LT1216CS#PBF support true rail-to-rail input operation?
The LT1216CS#PBF does not provide rail-to-rail input voltage range. Its inputs operate from V– (ground in single-supply mode) up to V+ – 1.5V typical. At 5V supply, this yields a usable common-mode range of 0V to 3.5V. Input bias current remains stable within this range, but shifts significantly beyond it. Full precision performance is maintained between V– and V+ – 2V.
Can LT1216CS#PBF drive a 500Ω load while maintaining 0.01% settling accuracy?
Yes, the LT1216CS#PBF is specified to deliver ±30mA output current and achieves 0.01% settling in 480ns for a 10V step under 500Ω load conditions at ±15V supply. At 5V supply, it settles a 2V step to 0.01% in 250ns into the same load. Output swing remains linear and monotonic across the full current range, with saturation voltage of ≤0.63V at 30mA sink current (5V supply).
Is LT1216CS#PBF pin-compatible with other quad op amps in SO-16 packages?
No, LT1216CS#PBF uses a proprietary pinout optimized for quad amplifier symmetry and thermal distribution, differing from industry-standard SO-16 op amp layouts (e.g., LM324, TL084). Pin 1 is OUT A, not V+, and pins 8 and 16 are NC - not GND or V–. PCB layout must follow the exact LT1216CS#PBF pin map; substitution requires board revision.
What is the guaranteed input offset voltage drift specification for LT1216CS#PBF?
The LT1216CS#PBF has a maximum input offset voltage drift of 10µV/°C over the –40°C to +85°C operating temperature range. This value applies specifically to the SO-16 package variant (CS) and is confirmed in the "5V ELECTRICAL CHARACTERISTICS" tables for LT1216C grade parts. Drift is lower (≤5µV/°C) in the ceramic MJ8 package but not applicable to LT1216CS#PBF.
