Product details
Overview
LT6600IS8-10#TRPBF from Analog Devices (formerly Linear Technology) is a fully differential amplifier with integrated 4th-order 10MHz Chebyshev lowpass filter, designed for antialiasing and signal conditioning in high-speed ADC/DAC interfaces. It delivers 82dB SNR at 3V supply with 2VP-P output, supports programmable gain via two external resistors, and sets output common mode voltage via VOCM pin. Used in cellular base station receivers and medical imaging front-ends.
For engineers reviewing the LT6600IS8-10#TRPBF datasheet, LT6600IS8-10#TRPBF pinout, LT6600IS8-10#TRPBF application, or LT6600IS8-10#TRPBF equivalent, this page provides verified specifications, SO-8 package terminal mapping, real-world distortion performance at 1MHz/5MHz, differential gain configuration guidance, and validated alternatives for 10MHz antialiasing filter replacement.
Technical Context
The LT6600IS8-10#TRPBF integrates a proprietary differential amplifier stage followed by a fixed 10MHz 4th-order lowpass filter with 0.5dB passband ripple. Its internal architecture eliminates need for external precision components to set cutoff frequency while retaining full control over differential gain (via RIN) and output common mode voltage (via VOCM).
It operates from single 3V, 5V, or dual ±5V supplies, features fully differential inputs/outputs, and maintains low distortion (88dBc 2nd harmonic @1MHz, 74dBc @5MHz) and 56μVRMS input-referred noise (10kHz–10MHz) across –40°C to +85°C industrial temperature range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Filter Cutoff Frequency | 10MHz - Fixed 4th-order Chebyshev response with 0.5dB passband ripple; no external components required. |
| Signal-to-Noise Ratio | 82dB - Measured at 3V supply, 2VP-P output, enabling high-resolution digitization of small signals. |
| Harmonic Distortion | 88dBc (2nd), 97dBc (3rd) @1MHz - Ensures minimal spectral contamination in baseband signal paths. |
| Input-Referred Noise | 56μVRMS (10kHz–10MHz) - Low-noise performance critical for preserving dynamic range before ADC sampling. |
| Supply Voltage Range | 3V, 5V, or ±5V - Single-supply operation down to 3V simplifies power design in portable and low-voltage systems. |
| Operating Temperature | –40°C to +85°C - Industrial-grade qualification ensures reliability in base station, test equipment, and imaging environments. |
| Differential Output Swing | 3.85VP-P (3V supply), 4.9VP-P (5V supply) - Sufficient headroom for driving modern 12–16-bit ADCs without clipping. |
Pinout & Package
LT6600IS8-10#TRPBF uses an 8-lead plastic SO (SO-8) package, rated for –40°C to +85°C operation. Exposed lead frame enhances thermal dissipation; θJA = 100°C/W on standard FR-4 board.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 (IN+) | Differential Input Positive | Accepts input signal referenced to external RIN; DC gain = 402Ω/RIN. |
| 2 (VOCM) | Output Common Mode Reference | High-impedance input setting average voltage at OUT+ and OUT–; bypass with 0.01μF ceramic capacitor. |
| 3 (V–) | Negative Supply Rail | Ground reference for single-supply operation; must be connected to PCB ground plane. |
| 4 (OUT–) | Differential Output Negative | Drives 100Ω load to AC ground; paired with OUT+ for true differential signaling. |
| 5 (OUT+) | Differential Output Positive | Complementary output to OUT–; together deliver filtered, level-shifted differential signal to ADC. |
| 6 (V+) | Positive Supply Rail | Accepts 3V, 5V, or ±5V supply; requires 0.1μF ceramic bypass capacitor to V–. |
| 7 (VMID) | Internal Mid-Supply Bias | Internally biased at VS/2; bypass to V– with 0.01μF capacitor for single-supply stability. |
| 8 (IN–) | Differential Input Negative | Completes differential input pair; matched impedance and layout critical for CMRR >61dB. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated Antialiasing Filter | Eliminates need for external RC networks or active filters-reduces BOM count and layout sensitivity in high-speed data acquisition. |
| Programmable Differential Gain | Set precisely via two identical external RIN resistors (e.g., 402Ω → gain = 1 V/V); avoids gain error from resistor matching tolerances. |
| Adjustable Output Common Mode | VOCM pin enables direct interface to ADC reference voltages (e.g., 1.65V for 3.3V ADCs), removing level-shifting amplifiers. |
| Low-Voltage Operation | Full performance at 3V supply enables use in battery-powered instrumentation and portable medical devices. |
| Industrial Temperature Range | Specified over –40°C to +85°C ensures stable gain, noise, and distortion in outdoor telecom and factory-floor applications. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar differential amplifier + lowpass filter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LT6600IS8-5#TRPBF | 5MHz cutoff frequency; same SO-8 package, –40°C to +85°C rating, identical pinout and gain programming. | Lower bandwidth suits sub-10MHz applications like audio ADCs or legacy wireless standards (WCDMA, TD-SCDMA). | Select when system Nyquist zone is ≤5MHz-reduces aliasing margin while maintaining identical layout and biasing. |
| LT6600IS8-15#TRPBF | 15MHz cutoff; otherwise identical electrical specs, package, and temperature grade. | Suitable for higher-sampling-rate systems (e.g., 30MSPS+ ADCs) requiring wider analog bandwidth before aliasing. | Choose for wideband instrumentation or radar pulse capture where 10MHz cutoff would attenuate desired signal content. |
Compared with LT6600IS8-10#TRPBF, the LT6600IS8-5#TRPBF trades bandwidth for improved stopband rejection below 5MHz, while LT6600IS8-15#TRPBF extends usable analog signal bandwidth-both retain identical gain control, noise, and thermal performance in the same SO-8 footprint.

FAQ
What is the exact filter topology and passband ripple of the LT6600IS8-10#TRPBF?
The LT6600IS8-10#TRPBF implements a 4th-order Chebyshev lowpass filter with a nominal 10MHz cutoff frequency and 0.5dB passband ripple. This topology is internally fixed and does not require external capacitors or inductors-ripple and cutoff are process-trimmed during manufacture and remain stable over temperature and supply voltage.
Can the LT6600IS8-10#TRPBF operate from a single 3.3V supply?
Yes, the LT6600IS8-10#TRPBF is fully specified and characterized for 3V operation, delivering 82dB SNR and 3.85VP-P differential output swing. Its input common mode range supports 0V to 1.5V (at 3V supply), and VOCM can be set to 1.65V to match typical 3.3V ADC references-no level-shifting circuitry needed.
How is differential gain programmed on the LT6600IS8-10#TRPBF?
Differential gain is set by two identical external resistors (RIN) connected from IN+ and IN– to the signal source. Gain = 402Ω / RIN. For unity gain, use 402Ω; for 2× gain, use 201Ω. The LT6600IS8-10#TRPBF's internal feedback network ensures accuracy independent of resistor tolerance when both RIN values match.
What is the maximum differential input voltage the LT6600IS8-10#TRPBF can handle without clipping?
The LT6600IS8-10#TRPBF begins limiting at ~2VP-P differential input and exhibits noticeable compression above 3.5VP-P. At unity gain and 5V supply, the guaranteed linear output swing is 4.9VP-P differential-so maximum clean input is ~4.9VP-P. For 3V supply, max linear input is ~3.85VP-P. Exceeding these levels increases harmonic distortion beyond datasheet specs.
Does the LT6600IS8-10#TRPBF require special PCB layout considerations for optimal noise and distortion performance?
Yes-critical practices include: (1) symmetric, matched-length traces for IN+/IN– and OUT+/OUT–; (2) solid ground plane beneath the device with low-inductance connections to V– and VMID; (3) 0.01μF ceramic capacitors directly at VOCM and VMID pins; (4) 0.1μF ceramic bypass from V+ to V–, placed within 2mm of pins 3 and 6. These minimize ground bounce and preserve CMRR >61dB and distortion specs.
