Product details
Overview
LM8207MT from Texas Instruments is an integrated TFT-LCD gamma correction and VCOM driver IC comprising 18-channel gamma buffers, a high-current VCOM buffer (300 mA short-circuit capability), and a temperature-compensated 1.295 V internal voltage reference. It operates from 6 V to 16 V supply, supports −40°C to +105°C industrial temperature range, and drives large capacitive loads in high-resolution LCD panels. Its primary system role is precision analog voltage distribution for pixel grayscale control and common electrode biasing.
For engineers reviewing the LM8207MT datasheet, LM8207MT pinout, LM8207MT application, or LM8207MT equivalent, this page delivers verified functional identity, validated 48-pin TSSOP package mapping, confirmed gamma/VCOM output current specs, real-world timing recovery metrics (200 ns VCOM, 400 ns gamma), and two technically documented alternative parts with explicit functional and application-level differences.
Technical Context
The LM8207MT integrates three functionally isolated analog subsystems: (1) 18 gamma buffers segmented into three optimized groups (buffers 1–2 rail-to-rail swing to VDD; 3–16 symmetric ±1 V swing; 17–18 swing to VSS), each with dedicated input voltage ranges and linear output current profiles; (2) a VCOM buffer featuring 10 MHz bandwidth, 4.5 V/µs slew rate, and stability with ≥100 pF capacitive loads; and (3) a programmable bandgap reference amplifier with 1% accuracy, 70 ppm/°C tempco, and output programmable up to VDD − 0.3 V.
Its architecture enables simultaneous, load-independent delivery of 18 discrete gamma voltages while maintaining fast transient response on the VCOM node during row-addressed pixel writes - critical for avoiding image flicker and crosstalk in large-format TFT panels operating at >60 Hz refresh rates.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gamma Channels | 18 independent buffers, grouped by output swing range (VDD→VSS+0.6V, VDD−1.2V→VSS+0.6V, VDD−1.6V→VSS) to match gamma curve position |
| VCOM Output Current | Sourcing/sinking up to 300 mA short-circuit; 150–160 mA linear range - sufficient for driving >10 nF panel capacitance with <200 ns recovery |
| Reference Voltage | 1.295 V ±1% (25°C), 70 ppm/°C drift - stable baseline for gamma resistor ladder and VCOM level setting |
| Supply Range | 6 V to 16 V operation - compatible with standard TFT panel DC/DC rails and LDO outputs |
| Operating Temp | −40°C to +105°C - qualified for automotive display modules and industrial HMI panels |
| Package | 48-pin TSSOP (7.0 mm × 12.5 mm, 0.5 mm pitch) - surface-mount compatible with automated PCB assembly |
| PSRR | 75–88 dB across gamma/VCOM/reference sections - suppresses supply noise coupling into grayscale and VCOM levels |
Pinout & Package
LM8207MT is housed in a 48-pin Thin Shrink Small Outline Package (TSSOP) with exposed thermal pad (not electrically connected). The package supports standard reflow profiles (230°C IR/convection, 260°C wave soldering) and provides θJA = 84°C/W thermal resistance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT_VREF | Programmable reference amplifier output - connects to external R1/R2 divider to set gamma/VCOM reference voltage |
| 3–21, 28–46 | IN_x / OUT_x (x=1–18) | 18 differential gamma channel pairs - IN_x receives gamma tap voltage; OUT_x drives column driver with low-Z buffered output |
| 24 | IN_VCOM | VCOM control input - accepts analog voltage (e.g., from reference amplifier) to set common electrode bias level |
| 25 | OUT_VCOM | High-current VCOM output - delivers stable DC bias to all pixel backplates; sinks/sources up to 300 mA |
| 12 | VDD | Main positive supply (6–16 V) - powers all internal buffers and reference circuitry |
| 37 | VSS | Negative supply (0 V ground reference) - return path for all analog sections and output drivers |
| 2, 22, 23, 26, 27, 47 | NC | No-connect pins - must remain unconnected per TI layout guidelines to avoid parasitic coupling |
| 48 | IN_VREF | Reference amplifier feedback input - completes closed-loop gain configuration with external resistors |
Key Features
| Feature | Design Value |
|---|---|
| Segmented gamma buffer optimization | Three output swing groups (1–2, 3–16, 17–18) minimize distortion across full gamma curve - prevents clipping at voltage extremes |
| VCOM transient recovery | 200 ns recovery time (CL = 100 pF) - maintains VCOM stability during rapid row-line switching, eliminating vertical banding |
| Reference programmability | OUT_VREF adjustable from 1.295 V to VDD − 0.3 V using two external resistors - enables flexible gamma/VCOM scaling without external DAC |
| Input offset voltage control | 1–10 mV max VOS across gamma/VCOM buffers - ensures <0.5% grayscale error across 18-bit equivalent voltage steps |
| Thermal robustness | Junction temperature limit +150°C with 84°C/W θJA - sustains continuous 16 V operation in sealed display enclosures |

Equivalent & Alternatives
The following parts are listed as comparable options for similar TFT-LCD gamma and VCOM driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LM8342MT | Same 48-pin TSSOP package; adds integrated DC/DC converter for VDD generation; no internal VREF - requires external reference | Eliminates need for external 16 V supply but increases BOM count; not suitable where board space prohibits DC/DC inductor | Select LM8342MT when system lacks dedicated 16 V rail and can accommodate DC/DC footprint; LM8207MT preferred for supply-constrained designs with existing 16 V source |
| TPS65105RGER | 16-channel gamma + VCOM + charge pump; 24-pin QFN; max VDD = 6.5 V; VCOM current limited to 100 mA | Lower pin count and smaller package, but insufficient for >10-inch panels requiring >200 mA VCOM drive | Choose TPS65105RGER for compact portable displays ≤7 inches; LM8207MT required for larger panels demanding 300 mA VCOM and 18-channel gamma fidelity |
Compared with LM8342MT and TPS65105RGER, LM8207MT uniquely combines 18-channel gamma buffering, 300 mA VCOM drive, and a programmable 1.295 V reference in a single 48-pin TSSOP - enabling higher-resolution panel support without external DC/DC or reference components.

FAQ
What is the maximum output current capability of the LM8207MT VCOM driver?
The LM8207MT VCOM driver delivers up to 300 mA short-circuit output current (both sourcing and sinking), with 150–160 mA linear operation range. This enables direct driving of large-panel VCOM nodes (≥10 nF) while maintaining <200 ns recovery time under transient load conditions, as verified in TI's SNOSAL5A datasheet Figure 10–11.
Can the LM8207MT generate gamma voltages beyond the supply rails?
No. The LM8207MT gamma buffers operate within defined rail-limited ranges: buffers 1–2 swing to VDD (positive rail); buffers 17–18 swing to VSS (negative rail); buffers 3–16 operate between VDD−1.2 V and VSS+0.6 V. None provide rail-to-rail or beyond-rail output - all outputs remain strictly within the VDD–VSS domain as specified in the Electrical Characteristics table.
How is the internal 1.295 V reference used in the LM8207MT?
The LM8207MT's 1.295 V bandgap reference feeds an internal amplifier whose output (OUT_VREF, Pin 1) is programmable via external resistors R1/R2 connected to IN_VREF (Pin 48). This allows precise setting of gamma and VCOM reference levels - e.g., 14.4 V output with R1 = 50.6 kΩ and R2 = 5 kΩ - as demonstrated in Figure 33 of the SNOSAL5A datasheet.
Does the LM8207MT require external compensation for VCOM stability?
No external compensation is required. The LM8207MT VCOM buffer is internally compensated for stability with capacitive loads up to at least 100 pF, as confirmed by frequency response plots (Figure 14–15) and transient recovery data (Figure 10–11) in the SNOSAL5A datasheet. Layout best practices (short traces, local 10 µF ceramic decoupling at VDD/VSS) ensure robust operation.
What is the operating temperature range for the LM8207MT?
The LM8207MT is rated for continuous operation from −40°C to +105°C ambient temperature, with junction temperature limited to +150°C. This industrial-grade rating is validated across all electrical parameters in the Operating Ratings table (page 2 of SNOSAL5A) and supports deployment in automotive dashboards, factory HMIs, and outdoor digital signage.
