Product details
Overview
LTC6910-1ITS8#TRMPBF from Analog Devices (formerly Linear Technology) is a digitally controlled, inverting programmable gain amplifier (PGA) in an 8-lead TSOT-23 package. It delivers precise 3-bit gain selection (0, 1, 2, 5, 10, 20, 50, or 100 V/V), rail-to-rail output swing, and 11 MHz gain-bandwidth product, enabling high-fidelity signal conditioning in space-constrained data acquisition systems.
For engineers reviewing the LTC6910-1ITS8#TRMPBF datasheet, LTC6910-1ITS8#TRMPBF pinout, LTC6910-1ITS8#TRMPBF application, or LTC6910-1ITS8#TRMPBF equivalent, key selection criteria include its 8nV/√Hz input voltage noise density at gain = 1, ±40°C to +85°C operating temperature range, and internal half-supply AGND reference for single-supply operation.
Technical Context
The LTC6910-1ITS8#TRMPBF implements a precision inverting amplifier topology with integrated digital control logic decoding three logic inputs (G2/G1/G0) to select one of eight discrete gain states. Its internal op amp features rail-to-rail output stage and a dedicated AGND pin that provides a stable mid-supply reference without external components.
It operates from single supplies (2.7V–10.5V) or split supplies (±2.7V–±5.25V), supports rail-to-rail input signals only at unity gain, and maintains low distortion (–90 dB THD at 10 kHz, gain = 10) across its full gain range under light loading (RL = 10 kΩ).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain Range | 0, 1, 2, 5, 10, 20, 50, 100 V/V - enables coarse dynamic range adjustment in automatic gain control loops |
| Gain-Bandwidth Product | 11 MHz - ensures usable bandwidth up to ~110 kHz at gain = 100 for sensor interface applications |
| Input Voltage Noise Density | 8 nV/√Hz at f = 50 kHz, gain = 1 - supports low-noise amplification of microvolt-level transducer outputs |
| Supply Voltage Range | 2.7 V to 10.5 V total - compatible with 3.3 V and 5 V single-rail systems and ±5 V dual-rail designs |
| Operating Temperature | –40°C to +85°C - qualified for industrial-grade embedded instrumentation and test equipment |
| Output Swing | Rail-to-rail - delivers full dynamic range into high-impedance ADC inputs without level-shifting circuitry |
| THD + Noise | –90 dB at 10 kHz, gain = 10, RL = 10 kΩ - meets audio and precision measurement SNR requirements |
Pinout & Package
Package: 8-lead TSOT-23 (ThinSOT™), 1 mm profile, surface-mount. Pinout validated per Linear Technology datasheet revision 6910123fb (Page 2, Pin Configuration).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OUT) | Inverting amplifier output | Delivers rail-to-rail amplified signal; drives ADC inputs or downstream analog stages directly |
| 2 (AGND) | Analog ground reference | Internally generates stable mid-supply voltage (e.g., 2.5 V @ VS = 5 V); may be overdriven by system reference |
| 3 (IN) | Inverting input | Accepts differential or single-ended input; input impedance varies with gain setting (10 kΩ at G = 1) |
| 4 (V–) | Negative supply rail | Connects to ground (single supply) or negative rail (dual supply); required for proper biasing |
| 5 (G0) | Digital gain control bit 0 | LSB of 3-bit code; logic high = 1, logic low = 0; TTL/CMOS compatible thresholds |
| 6 (G1) | Digital gain control bit 1 | Mid-bit of 3-bit code; defines gain steps alongside G0 and G2 |
| 7 (G2) | Digital gain control bit 2 | MSB of 3-bit code; selects major gain group (e.g., 10–100 V/V range) |
| 8 (V+) | Positive supply rail | Accepts 2.7–10.5 V; powers internal op amp and digital logic; requires local 0.1 µF bypass |
Key Features
| Feature | Design Value |
|---|---|
| 3-bit digital gain programming | Enables microcontroller-driven gain switching without external DACs or relays |
| Internal half-supply AGND reference | Eliminates need for external resistor divider or reference IC in single-supply configurations |

Equivalent & Alternatives
The following parts are listed as comparable options for similar programmable gain amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AD8251ARMZ | 4-channel, SPI-controlled PGA; 10 MHz GBW; higher quiescent current (4.5 mA); 16-lead QFN | Requires serial interface and additional decoupling; better suited for multi-channel synchronized gain control | Select when SPI configuration, channel count, or lower gain error (<0.05%) outweighs size and power constraints |
| MAX4208ETA+ | Single-supply, rail-to-rail I/O PGA; 3-bit parallel control; 10 MHz GBW; 10-lead µMAX package | No internal AGND reference; requires external bias network for single-supply use | Select when footprint compatibility with legacy µMAX layouts is critical and AGND generation is handled externally |
Compared with AD8251ARMZ and MAX4208ETA+, the LTC6910-1ITS8#TRMPBF offers the smallest footprint (TSOT-23), lowest input noise (8 nV/√Hz), and integrated AGND-making it optimal for ultra-compact, low-noise, single-supply sensor interfaces where parallel control suffices.

FAQ
What gain settings does the LTC6910-1ITS8#TRMPBF support?
The LTC6910-1ITS8#TRMPBF supports eight discrete inverting gain settings: 0, 1, 2, 5, 10, 20, 50, and 100 V/V, selected via the 3-bit parallel digital inputs G2/G1/G0. Gain = 0 provides high-impedance output disable. All gains are specified with ≤0.1 dB error at 25°C and ±5 V supply, and remain stable across –40°C to +85°C.
Does the LTC6910-1ITS8#TRMPBF require external components for single-supply operation?
No. The LTC6910-1ITS8#TRMPBF integrates an internal resistor divider that generates a precise half-supply voltage at the AGND pin-enabling true single-supply operation without external bias networks. A 1 µF capacitor is recommended between AGND and ground for stability, but no resistors or references are needed.
What is the maximum operating temperature range for the LTC6910-1ITS8#TRMPBF?
The LTC6910-1ITS8#TRMPBF is rated for continuous operation from –40°C to +85°C (Industrial grade, "I" suffix). This range is fully specified for all electrical parameters including gain accuracy, offset voltage, and THD. Junction temperature must not exceed 150°C under any condition.
How does the LTC6910-1ITS8#TRMPBF handle rail-to-rail input signals?
The LTC6910-1ITS8#TRMPBF supports rail-to-rail input signals only when configured for unity gain (G = 1). At higher gains, the linear input voltage range contracts inversely with gain magnitude-for example, ±2.5 V input range at G = 1 shrinks to ±25 mV at G = 100 with ±5 V supplies. Input common-mode range remains limited by AGND voltage.
Can the LTC6910-1ITS8#TRMPBF drive a 500 Ω load effectively?
Yes, but with reduced output swing and increased distortion. At G = 1 and ±5 V supplies, the LTC6910-1ITS8#TRMPBF delivers ±4.8 V swing into 10 kΩ but only ±4.3 V into 500 Ω. THD degrades from –90 dB to –77 dB at 100 kHz under the same heavy load. For 500 Ω drive, verify output compliance and distortion in final layout with proper thermal management.
